Beginning of New Generation of High-Energy Electron-Scattering Experiments

EXPERIMENT E142 CAPTURES NEUTRON SPINby Emlyn Hughes

DURING A DEMONSTRATIONto prove its robustness, a replica ofthe thin-window glass target cellto be used in experiment E142shattered into pieces when bangedagainst a metal table. The audienceat the 8 AM Technical Divisionmeeting burst into laughter. How-ever, the bad luck for experimentE142 ended there. During theexperiment's seven-week run lastNovember and December, almosteverything worked smashingly (nopun intended), and not one targetcell blew up in the electron beamdespite long exposures to highradiation. Experiment E142 markedthe beginning of a new generationof high-energy electron-scatteringexperiments in End Station A.

After completing pioneeringwork in 1982 on experiments tostudy the spin of the proton, SLACended its program of running high-energy polarized beams to End Sta-tion A and focused on theconstruction of the SLC. However, in1987, CERN ran an experiment scat-tering polarized muons (particleslike electrons but heavier) andfound that the standard theory onthe proton spin was wrong. TheCERN experiment generated a hugeinterest in the field, with a few hun-dred theoretical papers trying toexplain the results. Especially rele-vant to the discussion was whatcould be learned from the neutronand its spin. Thus began a three-way race between muon experi-

ments at CERN and electron experi-ments at SLAC and DESY.

Experiment E142 at SLAC is thefirst measurement studying theneutron spin by scattering high-energy polarized electrons off apolarized 3 He gas target. 3 He is anatom consisting of two protonsand one neutron. Neutrons bythemselves are extremely hard tocontain. But when they are insidean atom like 3 He, they can bestudied since 3 He is easy to handleand put in a bottle. When the 3 Heatom is polarized, the neutron spinlines up in one direction. The spinsof the two protons, on the otherhand, line up in opposite direc-tions to one another. The effects ofthe two proton spins cancel oneanother out, leaving only thepolarized neutron. Therefore, apolarized 3 He target is a goodmodel of a polarized neutron target.

Beginning last November,experiment E142 ran using the fullSLAC Linac. The experimentrequired special pampering fromthe operators, since the electronbeams for fixed-target experimentsrequire higher currents. Since ahigh-energy, polarized fixed-targetbeam had not been run in over adecade, it was quite a feat that theentire start up was accomplishedin one week of beam tuning. Thefinal beam stability was far betterthan previous polarized beams ofpast End Station A experiments.The improvement can be attributedto the major upgrades done for run-ning the SLC over the past years.

Among the milestones in theexperiment were: data collectedwith the highest energy ever deliv-ered to End Station A (25.7 GeV),the most stable polarized beam to

KASE RECIPIENT OF LANIDAUER AWARDLAST MARCH, just a month after returning to SLAC,Ken Kase learned that he had been selected to receivea nationally recognized award for his work in radia-tion physics. The 1992 Robert S. Landauer, Sr. Memor-ial Lecture Award, named for the pioneering educatorof radiological physics, was formally presented to Kenfor "...distinguished contribution to the field of Radio-logical Physics and Radiation Health Protection." Theaward presentation was held in May 1992 by the Mid-west chapters of the Health Physics Society and theAmerican Association of Physicists in Medicine.

In his lecture for the event, "Radiation Dosimetry:History, Challenges, and New Directions," Kenstressed that new concerns in radiation dosimetryneed to be addressed and that "We need to continueto be innovative in calculating and measuring radia-tion dosage."

As head of the ES&H Division's Radiation PhysicsDepartment, Ken is responsible for ensuring that newexperiments and experimental equipment complywith all SLAC and DOE radiation safety policies. Thus,Ken is constantly examining unusual challenges in theradiation physics field.

Ken began his career as a Health Physicist at theLawrence Livermore National Laboratory and thenjoined SLAC as a Health Physicist from 1969 to 1973.During that time he received his Ph.D. in Biophysicsfrom Stanford. Most recently, Ken was a professor ofRadiation Oncology and the Director of Physics,Department of Radiation Oncology, at the Universityof Massachusetts Medical Center.

When Ken decided to change the emphasis of hiscareer from clinical medical physics back to research-oriented radiation physics, he knew that he wanted toreturn to SLAC.

Ken's distinguished 30-year career includes the follow-ing highlights:

e Recipient of several awards, including the EldaAnderson Award in 1978 from the Health PhysicsSociety.

* Research in medical physics, biophysics, andhealth physics.

® Certification by the American Board of HealthPhysics and the American Board of Radiology.

* Training programs at Harvard, two schools ofthe University of Massachusetts, and San Jose StateUniversity.

* Associate editorship of both the Health Physicsand Medical Physics Journals.

® Author of numerous scientific papers. Ken alsohas edited a three-volume set on radiation dosimetry,and has co-authored a book on the same subject. Healso wrote a chapter on dosimetry of radon in the lungfor a book entitled Environmental Radon: Occurrence,Control ,and Health Hazards.

* Board Membership of the National Council onRadiation Protection and Measurement, for which healso chairs one committee and serves on two others.

F Fellowships with the American Association ofPhysicists in Medicine, the American College of Radi-ology, and the Health Physics Society.

WHAT IS VOICE MAIL AND WHY DOYOU NEED IT?by Dona Jones

VOICE MAIL SUBSCRIBERS AT SLAC now num-ber approximately 700. If you're not presently usingVoice Mail and want to know more about it, maybethe following questions and answers will help clarifywhat this service can do for you.

What Is Voice Mail?Voice Mail is an electronic voice-messaging system

that provides an easy, fast and dependable way to com-municate with people both inside and outside yourorganization performing the same function, and more,as your telephone answering machine without an exter-nal device. If you are not available to take calls, VoiceMail plays your personal greeting, takes messages auto-matically and stores them for pickup at your conve-nience, no matter where you are. If you are sick or planto be away from SLAC, you can change your personalgreeting every day, giving callers accurate informationabout when you will return. If you want to have yourcallers speak to a live person rather than leave a mes-sage, Voice Mail offers the option to press "0" and yourcallers will be forwarded to a secretary's telephone, inmost cases, or you can specify the number of someoneelse in your office to call in your absence.

INTEGRATING CAD/CAM WITH OUR FUTUREby Carl Rago

THE MECHANICAL SYSTEMSpart of the Technical Division,with indirect support from theMechanical and Industrial Engi-neering departments at Stanford,is proposing changes in our tradi-tional approaches to mechanicaldesign and production. Utilizing avariety of high-tech tools, we aredeveloping a tailored and integrat-ed approach to the production ofinstruments and mechanicalequipment. This new mechanismprovides a consistent vehicle tocarry projects from their initialconcept through design, manufac-turing, and quality assurance, and

tlon together into an cieallzea sys-tem. This new managementinitiative, essentially a reorganiza-tion of workflow, is a powerfulconcept that improves all aspectsof working relationships and pro-vides a variety of secondary bene-fits to all involved parties.

The status of the Americanmachine tool industry generallydeclined during the past fewdecades, but SLAC's demand forhigh-quality, extremely accurate,and sophisticated designs andequipment steadily increased. Asthe formidable machine tools usedfor production of the linac aged,the Mechanical FabricationDepartment (MFD) turned to high-tech solutions to meet changingdemands and dwindling person-nol rocn11rr cV'I LICJ1 I C t-O L1 C-

(Cont'd. from p. 6)

machine tools came to SLAC. Tosupport these new machine-tools,a line-code-driven software systemcalled Automatic ProgrammedTools (APT) was installed on theSCS mainframe. Machine-tooloperations were coded-usuallyby specially trained machinists-to match a programmer's interpre-tation of a blueprint. APT was aproductive and versatile system,and SLAC slowly expanded its useof CNC machines under the tute-lage of APT.

Production improvements fos-tered by APT were balancedagainst a system complexity thatseverely limited the input ofmachinists, virtually isolatingthem from the design process.Only select staff had access to thesystem, and design changesfocused on necessary correctionsrather than specific improvements.Engineers and designers similarlyremained isolated from the pro-duction process. Communicationand constructive interplay rarelyoccurred, thus abetting the tradi-tional us-and them-organization.

In the eighties, a re-examina-tion of the manufacturing process,and innovations, and improve-ments in computers and softwareled to techniques which includesdesigners, engineers, and machin-ists in the production process. Bet-ter, cheaper, and faster becamebywords of a new way to work,and through interplay betweendesign and production personnel,the integrated system is a reality.

The platform for an integratedsystem at SLAC is provided by theIntergraph Corporation. Initiallylimited to a Computer AidedDesign/Computer Aided Manu-facturing (CAD/CAM) system,Intergraph first found its way toSLAC in design groups and wassoon being evaluated by MFD. Thefirst operational Intergraph sta-

tions were crude and difficult tooperate by today's standards, andmany years away from our expec-tations. As a result, the fully opera-tional (and familiar) APTcontinued as the preferred systemfor a number of years.

In the last three years, designand manufacturing personnelworked hard to improve and vali-date the Intergraph system as aproduction tool. We have demon-strated engineering models thatpassed through design into pro-duction with fully functional andpractical features. Much hardwareand software has been added andchanged, but the greatest changehas been our increased focus onthe overall interrelationship of thedesign/production processes.

We now have a workable Inter-graph CAD/CAM system. Ourshort-term goals are to continue todemonstrate and expand the useof the system, and to install themetrics that will direct continualimprovements as SLAC's technolo-gy and demands change. Our ulti-

mate goal is a system which makesthe best use of computers and newtechnology-not only for the sin-gle-part phase of the design/pro-duction process, but also for theentire process.

The benefits of a successfulycoordinated operation are evident.Documentation, maintenance,traceability, cycle time, and costare all potentially improvedthrough the application of an inte-grated system. Increased involve-ment through the CAD/CAMsystem also brings greater satisfac-tion (and less general frustration)to every staff member throughimproved understanding andincreased respect for a coworker'srole in a project. SLAC must matchthese tools with foresight and con-sistent direction to turn technolog-ical innovation into continualimprovement and a practicalframework for the future.

SSRL STUDIES RADIOACTIVE WASTE PROBLEMA NEW FACILITY at the Stanford Synchrotron Radi-ation Laboratory uses its x-ray beams to study thestorage of radioactive wastes. In an effort to determinehow to protect the earth from this contamination,Stanford geologists Gordon Brown and George Parkshave organized the Center for Environmental andEnergy Related Science and Technology.

"There have been all sorts of hare-brained schemesto get rid of waste," says Brown. "Put it in the oceans,shoot it off into space in rockets." But these also canbackfire, spewing contamination into the environment.

So long-term storage appears to be the only solu-tion. It has entered the public spotlight recently asnuclear power plants try to handle billions of gallonsof waste which will remain radioactive for at least10,000 years.

Nuclear power plants now store their hazardouswaste temporarily on-site in huge vats. A plant inHanford, Washington holds 177 million gallons-enough to fill about a thousand Olympic-sized swim-ming pools-in metal tanks. The liquids have beenmixed and transferred so many times that plant man-agers no longer even know what kinds of materialsare in each tank.

"They have a very complex mixture of stuff andthey don't know what it is," says Brown. "There aretanks up there that are burping hydrogen. Big burpsof hydrogen. This could be very explosive."

A long-term storage remedy is clearly needed. Thecurrent plan is to bury all the waste in huge tanksdeep inside Yucca Mountain in Nevada, hoping thetanks will not be disturbed for the next ten millennia.

But Brown worries more about the radioactivewaste migrating away from the site on its own, andless about people inadvertently digging up the tanks.

"They want to put the waste in a place with theleast seismic activity, the least chance of a volcaniceruption, the least rainfall, the least chance of flood-ing," he says. "But this is not foolproof."

The waste itself can eat through the tanks, causingthem to leak pollution. Groundwater flowing by could

carry the waste away and contaminate wells and rivers.Brown thinks burying the waste is a good solution,

but additional barriers are needed. "We assume thatwater will come in contact with the waste at somepoint," he says. So he wants to ensure that the waterwon't pick up the waste as it flows by.

Water absorbs different metals and compounds indifferent circumstances, just as salt dissolves in hotwater more quickly than cold. So different metalsmight dissolve more quickly in water that is moreacidic. Flowing water may or may not pick upradioactive waste depending on these factors. Buryingwaste in conditions where it will never dissolve inwater could effectively contain the waste.

The Center uses intense x-rays, known as synchro-tron radiation, to study what dissolves in what. The x-raysbounce off samples made of some radioactive materi-al, water and perhaps clay or concrete. Re-searcherscan tell, on a molecular level, whether the radioactivewaste sticks to the clay or dissolves in the water.

Synchrotron radiation is necessary because it is theonly x-ray source that does not require the sample tobe in a vacuum, which would be impossible forBrown's samples, which include water.

The Center has so far found that some hazardouswastes bind tightly to iron oxides when placed inhighly acidic solutions.

"So using iron oxides," says Brown, "might be aneffective barrier."

The Center hopes to find similar barrier possibili-ties for the many types of nuclear waste-uraniumand cesium, to name just two.

"We are trying to understand the effect of all thesedifferent variables on the metal absorption-whatsticks and what doesn't stick, and how strongly theystick," says Brown.

Once all these variables have been determined,Brown hopes to build detailed computer models todetermine how far the waste might travel in groundwater, and whether it can be contained.

AFFIRMATIVE ACTION: AN EXPLANATIONSUEVON GEE, SLAC's Affirma-tive Action Officer, recently pre-sented a brief background of EqualEmployment Opportunity (EEO) ata noontime talk sponsored by theWomen's Interchange at SLAC(WIS). The EEO Program, formedas a result of the Civil Rights Actof 1964, deals with non-discrimi-nation in the workplace. This per-tains to all aspects of employment,such as selection, promotion, ter-mination, and benefits. The Affir-mation Action (AA) Program, theresult of a Presidential order,focuses on past discrimination andits effect on protected groups.

SLAC's Affirmative ActionOffice reports to the LaboratoryDirector and has a peer relation-ship with the Personnel Depart-ment and the Associate Directors.The Director presides over anyconflicts among these groups.

The challenge faced by SueVonin implementing both EEO and AAis to correct the effects of past dis-crimination while practicing non-discrimination. As an example, shedescribed how EEO/AA worksduring the employment selectionprocess. During the interview andselection process, EEO (nondis-crimination) is in effect. AA mayenter into an employment selec-tion when two candidates aredetermined to be qualified. Under

EEO no one group has preferenceover another for selection, promo-tion, termination, or layoff.

In answer to a question regard-ing the AA Office's involvement inselection of physicists, SueVonindicated that physicists on atenure track are selected by theStanford University faculty andthe AA Office is not involved. If aphysicist is on the staff track, how-ever, SueVon may be involved inthe selection process via the nor-mal requisition process.

SueVon said that given the longstanding of EEO/AA, she is disap-pointed with the progress that thiscountry has made. There has beenmore progress in EEO than in AA.This may be due to the fact thatsome people do not agree that AAis the best approach to equality.For instance, in the last ten yearsmuch of the funding for communi-ty organizations and job trainingprograms has been cut back oreliminated.

SLAC's Affirmative Action,Summer Science Program, YouthOpportunity Program, WorkStudy Program, and Apprentice-ships are examples of programsthat historically have been aimedat minorities and women. SLACalso participates in various pro-grams such as the National Con-sortium for Engineering whichencourages minorities to get agraduate degree in engineering.

Because these programs are noton the critical path for high-energyphysics research, their support andsurvival is dependent primarily onthe availability of resources andthe overall SLAC managementcommitment to EEO/AA.

SueVon reported that ten yearsago 17% of the SLAC populationwas female. Today 21% is female.The Affirmative Action Office hashistorically focused on diversity inoccupational areas rather than onincreasing numbers. SueVon stat-

SueVon Gee, SLAC Affirmative ActionOfficer.

ed that diversity, as well asprogress in numbers, is challeng-ing because the following factorsaffect success and rapid progress:

· Opportunity for change-theturnover rate is traditionally lowat SLAC (currently at 6.8%).

* Support is dependent onmanagement and its willingnessCEto make EEO/AA a high priority.

* Availability-what is theeducation system and labormarkCEet turning out with regardto minorities and women? It is not-ed that in the last ten years all stu-dents (particularly minorities andwomen) are moving away fromthe sciences and going into busi-ness, law, and social science stud-ies. This trend affects the availablepool of minorities and womenfrom which SLAC can selectemployees.

SueVon finds it more effectiveto deal with individuals ratherthan groups because there is ahigher probability of finding a spe-cific solution. If you would like tofind out more about AffirmativeAction or you have specific ques-tions, feel free to schedule anappointment with SueVon Gee atext. 2967.

The source of this crisis is two-fold: many long-time membersare retiring, and there have been alarger than usual number of seri-ous problems that needed our helpduring the last six months. Recent-ly, it was necessary to turn downindividuals whose emergency con-ditions would certainly have quali-fied them for assistance, had webeen able to give it. The simplefact is, we had no money to give.

SERA is a non-profit, tax-deductible charity formed by SLACemployees in 1968 to aid those ofthe SLAC community whose finan-cial condition has become desper-ate due to emergencies beyondtheir control. It is entirely run byvolunteers, who serve an 18-monthterm, and ALL donations go di-rectly to those in need-there areno overhead costs.

Presently, approximately 80percent of the grants are repaidwithin one or two years. SERA hasrecovered from its zero balance,but is still seriously low in fundson hand. The decrease in dona-tions due to retirement of ourmembers is going to continue, asthose who have long supported us

take early retirement, and it is rea-sonable to expect that in thesehard times the need will continueto be great.

SERA is primarily dependent onthe donations of its membership.We urge you to join us in thiseffort. A $6 lump-sum donation, ora payroll deduction of 50 cents permonth, makes you a full votingmember of SERA. Of course, a larg-er lump-sum or monthly donationwould be most welcome (the cur-rent average is $2.50 per month).Some of you will prefer to make alump-sum donation, while othersprefer to authorize a modest pay-roll deduction-in both cases yourdonation is fully tax-deductible. Ifyou who are already a member ofSERA, you might consider anincrease in your current donation(even a modest increase wouldhelp greatly).

SERA has always stood ready tohelp those of in need of a helpinghand. Now SERA needs your sup-port. Please send your lump-sumdonation to SERA in care of ZorabVassilian, Treasurer (ext. 2464), atMS 12, or clip the coupon below,fill in your donation, and drop it inthe mail today!

Joan Retires: Another Earth-Shaking Event

c-

WAS THAT AN EARTHQUAKEthe evening of January 15, or theculmination of Joan Dammann's27 years of service as the nurse inthe Medical Department?

Whatever the cause, during abrief sunny respite from twoweeks of torrential rains, approxi-mately 150 employees, specialguests from Palo Alto MedicalClinic (PAMC), and sixteen faith-ful retirees met at the main hall ofIR8 for a luncheon send-off forJoan. Thanks are due to the many

people who were instrumental inarranging this function. It wasgreat fun working with all of you.

Glenn Tenney and Doctor Mar-garet Deanesly presided over theceremonies, calling upon J. BertRose, Assistant Administrator ofthe Palo Alto Medical Clinic, BurtRichter, Director of SLAC, and PiefPanofsky, Director Emeritus ofSLAC, for their words of wisdomand good wishes.

Joan joined the staff of thePAMC in 1966. She and DoctorRobert Armbruster were instru-mental in setting up the MedicalDepartment here at SLAC, withPAMC providing most of the sup-plies.

In his farewell address J. BertRose stated that "Joan (or Joan ofSLAC, as he has called her for 27years), was a most important partof the clinic at SLAC. She kept ittogether and worked towards pro-viding excellent medical care forthe patients and employees." Hecontinued, "Her success wasexemplified by the number of peo-ple from all walks who appearedat her retirement party."

Joan, a Certified OccupationalHealth Nurse, is affiliated with theCalifornia El Camino Real Associa-tion of Occupational Health Nurs-es (AOHN), South Bay, and theNorthern California, CaliforniaState, and American (national)AOHN. She served on past boardsof the Mountain Western AOHN asPresident and Secretary.

Joan also served on the SLACSafety Committee and set up vari-ous health-oriented programs overthe years for the employees. Sheprovided First Aid coverage atannual on-site Family Days.

Joan was presented with aSLAC watch by Burt Richter. Shewas also given a coveted beam treeand some crystal goblets from theattendees.

Doctor Margaret's farewell toJoan, which she offered at theretirement party and reiterated onJoan's last official day here, wasbased on these popular songs:Thanks for the Memories, I'm soGlad We've Had This TimeTogether, and, Joan, You Are theWind Beneath My Wings.

Best wishes, Joan!Marion Lisotto
