2006 Run planning
• Short run with only 3 months of physics.• AD run extended to cover weekends.• 2650 hours total (2040 physics) are scheduled, to be compared
with 3400 in 2004.• OP/AD-LEIR section will cover either AD or LEIR operation,
including LEIR commissioning.• AD: ops crew = 5 specialists on-call Mon 07:00 – Mon 07:00
24h/24. Shiftwork on AD during startups and md:s.

Equipment tests
• Key dates:– 24/4: search + closure of AD ring and Target Area
• AD Hall remains in free access unless major problems• Target area in controlled access (special access procedure)• Controlled access to AD ring if needed
– 24/4 – 14/5: HW tests + cold checkout– 15/5: startup w. production beam– No critical days

Electron cooler/Vacuum:
• Replacement of / add missing NEG:s• Repair of orbit pickups• Replacement of cathode• Alignment • Improvement of orbit correctors 2904/2917: Study
completed, but no budget to go further

Electron cooler/Vacuum
• Install non-magnetic support for VVS3105• Install vacuum chamber in place of K35• Repair of BIPM sect 42• Isolate 8000-line• Modify VVS in ej. line

News for 2006
• ACE (AD-4) has requested 500 MeV/c pbars for cell irradiation.• Approval by SPSC in Jan. 06 ??• This implies significant changes to the AD cycle:
– Tests of SW during eq.tests– Use of some of the planned md-periods during the year for further tests– Final setting-up followed by physics to be done at end of 2006 run to avoid
disturbing the other users; 160 hours in total requested (setup + physics).• If unexpected problems, ACE can go back to 300 MeV/c
operation on short notice

News for 2006
• Tests of ATRAP:s new 3T solenoid in 2004 revealed that no beam can be transferred to ATHENA due to the stray field
• A new H dipole will be installed to compensate (DE0.DHZ87)
• Tests during startup

Beam requirements
• 26 GeV/c beam needed as from 15/5• No use of 3.57 GeV/c protons is planned, BUT:
– In case of serious problems, we might have to resort to proton operation with AD in reverse polarity; 3.5 GeV/c tst beam should be available on fairly short notice

Operation from ccc
• Start-ups and md:s will continue to be carried out from the ACR
• As far as tools/diagnostics, no major problems can expected for ccc operation; CCC=MCR as seen from the AD
• The required AD modifications for efficient operation from the ccc were:
– Improve stability with improved steering dipoles for pbar/e-beam alignment
– Replace MWPC:s by non-destructive BPM:s in the ejection lines
• None of the requested modifications were carried out – many trips to/from ACR, more downtime and delays can be expected
