ADMIRAL WATKINS TOURS FACILITY

Jonathan Dorfan (right) explains features of a mock-up of the proposed SLAC/LBL B Factory to Admiral JamesP. Watkins, Secretary of Energy, on Watkins' May 26 visit. Listening are (I. to r.) Donald Pearman, Acting Directorof the DOE Office of Administration; Barry Daniel (partially hidden), Director of the DOE Office of Public Affairs;David Hitlin, Professor of Physics at Caltech; and SLAC Director Burt Richter.

Budget UpdateCONTINUING OUR coverage ofbudget developments, following is ashortened version of Burt Richter'sJune 12 All Hands memo.

I have some encouraging newsfrom Washington, DC. The HouseAppropriations Committee haslargely endorsed the President'srequest for funding of the basehigh-energy physics program,which includes about $143 millionfor SLAC operations, equipmentand other expenses. Given thebudget pressures, we are fortunateto obtain such a result.

The Committee also acknowl-edged the excellent work SLAC,LBL and our user community have

been doing on the B Factoryproposal to the Department ofEnergy. Although they did notallocate specific funds forconstruction in FY93, they did takenote of the B Factory, thereby indi-cating a certain sympathy for theproject. The Committee alsogranted approval to move into theprimary engineering phase (DOEwilling) which would normallyrequire project approval:

Because of budget constraints, theCommittee has not provided funds toinitiate significant new programs.[However] the Committee has noobjection to a low level of research andengineering to develop this proposalfor possible future submission.

In this round of the budgetaryprocess SLAC also enjoyed bipar-

tisan support from the entire Cali-fornia Congressional delegation,led by Congressmen Don Edwardsand Carlos Morehead. Withoutthis added support, SLAC couldhave easily fared much worse.

towards in the next 30 years: theFinal Focus Test Beam, the newexperiments in End Station A, TauCharm in Spain, the B Factory, theNext Linear Collider, many excit-ing possibilities at the Stanford Syn-chrotron Radiation Lab, which willsoon join the family, and no doubtother good surprises.

Record Crowd for Fitness Day

Camaraderie more than competition was the driving force for the crowd of walkers andstriders as they completed the annual Employee Fitness Day walk.

A CROWD OF 238 PEOPLE spentthe noon hour on May 20 walkingmore than two miles in the thirdannual Employee Fitness Day.Among them was probably theyoungest participant ever, Chrisand Bob Traller's baby Robert in hisstroller. The guards cheered usalong as the largest turnout yet forthis event wound its way past theSector 30 gate, up and down andaround the observation road, andfinished back at the A&E parkinglot. The ice-cold drinks waitingthere were a welcome sight to thoseof us who were slightly overheated.

A competition is held each yearfor most creative costume, mostparticipants from a department,and 100% participation from adepartment. The following depart-ments won this year:

Most participants: KlystronMost creative costume: Opera-

tional Health Physics100% participation: A four-way

tie among Mechanical Engineer-ing, Travel, Mail Room, and Affir-mative Action was resolved with adrawing. The Mail Room won.

Costumes this year were excep-tionally creative. OperationalHealth Physics wore giant dosi-meters; Environmental Protectionand Waste Management tied theirgroup together with yellow cau-tion tape and carried giant hazar-dous waste labels; and AffirmativeAction disguised themselves as theMarx brothers.

It's not too early to startthinking about your distinctivecostume for next year, so encour-age your department to partici-pate, and we'll be looking for younext May.

Affirmative Action's interpretation of the Marxbrothers: Connie Courtney (Harpo); SueVonGee (Chico); Brent Hendry (Groucho).

WHEN LESS IS BESTWASTE MINMIIZATION PREVENTSpollution to our environment fromboth hazardous and nonhazardouswastes. We discussed strategiessuccessfully used to address reduc-tion of hazardous wastes (InteractionPoint, April-May 1992). Some of thefollowing suggestions for ways toreduce waste can be used at homeand on the job.

Nonhazardous WastesReducing the sources of waste gen-eration and recycling are the mainwaste reduction measures to use fornonhazardous wastes. It has beenestimated that approximately 25percent of SLAC's nonhazardouswaste is diverted for recycle to theStanford Recycling Center (SRC) orto SLAC's Salvage Department.SLAC cannot recycle all of its non-hazardous wastes, but it can improveits recycling efforts. Based on obser-vation of trash sent to site dumps-ters, some specific measures toincrease recycling are:

* Separate wet wastes (food stuffs)from recyclables such as whitepaper, newspaper, and other recycl-able papers. Consider using a desk-top collection box to accumulaterecyclable papers that can later beforwarded to a nearby SRC collec-tion container.

· Separate white paper from coloredpapers and junk mail (Note: coloredpaper, junk mail, and magazinesare all collected in a separate SRCcontainer. Use a nearby existingSRC collection container for coloredor mixed papers and consider usinga desktop collection box.

* Add empty plastic containersfrom milk, bottled water, and

beverages to the SRC collection con-tainers supplied by the Universityfor recycling glass.

* Cardboard and brown Kraftpaper should be neatly stacked (un-folded where practical) for pickupby Facilities staff in accordancewith agreed upon locations, oroutside existing trash dumpsters.

* Reuse Styrofoam packing beadsfrom incoming mail or parcels forrepackaging the goods that youplan to be stored or mailed.

* Send electrical equipment, scrapmetals, and wire (called whitegoods) to Salvage and not the trash.

Hazardous WastesConsider the following measures,particularly where technically andeconomically feasible. Keep in mindthat the cost of spill cleanup, wastedisposal and waste transportationcontribute to the potential or actualcost of using a hazardous materialor product.

* Substitute more hazardous materi-als with less hazardous materials.

* Buy only what you need to avoidgenerating unused out-of-datechemicals.

* Observe inventory control to avoidduplicate purchases and overstockingof raw materials or products.

* Check with the manufacturer to findout if the product or product contain-ers are recyclable, and the manufac-turer's arrangements and require-ments, if any, for container pickup.

* Segregate nonhazardous materialsfrom hazardous waste to reduce thevolume of hazardous waste disposal.

* Reduce the scale of an experimentor a project, where practical, to

reduce the volume of hazardouswaste generated.

* Promote in-line process controls orchanges to improve process efficiencyand to reduce the frequency of hazard-ous waste generated.

* Observe good spill preventionpractices by periodically inspectinghazardous material containers forleaks, by keeping container lidssealed, by using secondary contain-ment (Interaction Point, August1991), and by protecting or cover-ing containers to keep out the rain.

Effective, responsible wasteminimization requires everyone'scooperation. The results, lesswaste, and less threat to our envi-ronment, benefit us all. Let us knowabout your successes and ideas toimprove our efforts at SLAC.

BEE FACTORY SWARMS FOR BAY TO BREAKERSAT THE CRACK OF DAWN onMay 17,20 people donned bee cos-tumes to walk/run for 7.48 milescarrying a B Factory (hive) createdby Tony Bell and Mike Lateur-complete with bees (made by RuthConsul) and particles.

Queen Bee Priscilla Lukonorganized and expedited most ofthe arrangements of the centipedewith the help of her Lead Seam-stress Bee, Robbin Nixon. Manybehind-the-scenes worker bees didthe rest. The bees, walkers, run-ners and support group certainlydeserve sweet recognition. Let'snot forget Top Coordinator Bee,Eileen Derr, without whose effortsthis whole flight would neverhave gotten off the ground.

Elementary Introduction for a General Audience N extStandard Model Simply Stated WISTHE STANDARD MODEL of

particle physics is a phrase we see

and hear often, but how many of us

really know what it is? The recentnoontime lecture on by PatriciaBurchat answered that question in

layman's terms. Sponsored by the

Women's Interchange at SLAC (WIS),

the talk was aimed at a general

audience and was attended bymore than 80 people. Usingsnowball-throwing ice skaters toillustrate her talk, Pat explained theevolution of the standard model ofthe fundamental particles whichmake up all matter and the inter-actions between them. She dis-cussed the key ideas behind themodel, and both the questions itanswers and those it leavesunanswered.

Pat is an Assistant Professor ofPhysics at the University of Califor-nia at Santa Cruz. She has workedon the Mark II experiment at PEPand SLC and on the developmentof an asymmetric B factory. Avideotape of the presentation isavailable in the library. The fulltext of her talk is printed asSLAC-PUB 5835.

A color poster of the standardmodel is available from Science Kit,777 East Park Drive, Tonawanda,NY 14150-6782. For more informa-tion call 1(800) 828-7777.

ForumOn June 23, WIS presents SharonTraweek on Women in High EnergyPhysics Labs: Changes in Our Midst.Most of the jobs in these labs arehighly segregated by gender, andoften by ethnicity and class as well.How does this segregation shapeworking relationships between menand women and affect opportun-ities for women at national HEP labsin the US and Japan? How has thischanged over the last twenty years?What are the prospects for the nexttwenty years? These questions andmore will be addressed in the talk.

Traweek is an associate profes-sor at Rice University in Houston,Texas, and is the author of thebook Beamtimes and Lifetimes: TheWorld of High Energy Physics, basedon her anthropological study ofSLAC, Fermilab and KEK.

REMEMBERING JOHN KULP

JOHN KULP DIED on May 13 inLos Angeles, California. Retired justover two years ago, John came toSLAC in 1979 as a member of MainControl Center Maintenance, andlater worked with the AcceleratorMaintenance Special Systems groupon power conversion of fast pulsers.

He was a man of many andvaried experiences in life, espec-ially in electronics (no matter whatarea of electronics, John had someexperience with the circuit appli-cation). A Sergeant in the SignalCorps in World War II, he couldsend code at better than 35 wordsper minute. John held two antennapatents from his ten years in thephysics lab at Philco-Ford. He didmagnetometer surveys in Boliviawith French helicopter pilots for anItalian company. Putting Spanishendings on the Old French he

learned at the Sorbonne atter thewar, he developed a fine Spanishvocabulary. Always ready to helpsomeone, he later taught electron-ics to young students at theOpportunities IndustrializationCenter, a local job training centerin Menlo Park. He worked as atranslator of technical French andcould quote poetry in more thanten languages. He greatly enjoyedfishing and reading, especiallyscience fiction, loved to play guitarand sing German Lieder, and wasalways working on an electronicsor radio project after work. He wasa truly remarkable person and agood friend. Those of us who knewhim will miss him. He is survived bythree daughters, a granddaughterand a grandson.

VM CLASS AND XEDIT EXITTHERE IS AN IMMINENT CHANGE in the direction of computing atSLAC from the IBM mainframe system to a distributed computingenvironment, where a variety of machines will be used. Because of this,the introductory class which teaches people how to operate the VMsystem will be discontinued. Appropriate training will be offered afterthis transition period, when need and direction are clearer.

A distributed environment vastly lowers the cost while still offeringsimilar net power. However, handicaps include weaker security and theadded difficulty of disseminating uniform tools to the users. Solutionswill become clear when the computing direction at SLAC is better known.
