  18. TPC • Take out capacitors on all A/C ROC ALICE 2011-12 winter shutdown schedule - A.Tauro

  19. TPC heat screen • Check the loops for the thermal screen in week 6 (there was a leak) • We will need: • access to the TRD cooling plant • access to C side and A side of TPC • access to the miniframe and PP0 • Since the pipes are on the outside of the miniframe we would probably need a nacelle. ALICE 2011-12 winter shutdown schedule - A.Tauro

  20. TPC sectors 11 to 15 • Week 49: • Thu 8/12: displace FMD2 box. The box can be reinstalled anytime (at latest in week 5) • TPC A-14/15 (4 days anytime) • Week 3: move PMD to parking position (see next slide) • Week 4: • Mon 23/1 AM: disconnect and displace SPD box • Mon 23/1 PM: disconnect and displace SSD box • Tue-Fri: TPC A-11/12 (4 days) • Sat: put back and test SSD box • Week 5: • Mon 30/1: put back and test SPD box • Tue: move V0-FMD1 to parking position (PMD already in parking position) • Wed-Fri: TPC A-13 (2 and 1/2 days) + FMD2 survey + reinstall FMD2 box • Sat: move back and test V0-FMD1 • Week 6: • Mon 6/2: survey of V0-FMD1 ALICE 2011-12 winter shutdown schedule - A.Tauro

  23. TPC laser • Annual laser maintenance, 1-2 days. Needs normal power and cooling • Open mirror box below TPC sector A13 (bottom below TPC endplate) and possibly replace camera or mirror. 1-2 days. I want to do this because a weak picture from this mirror/camera makes C-side alignment difficult. Best done with L3 doors open. I believe access between the TOF and TPC should be OK. I need to be able to run the laser, so we need to mount the long laser pipe temporarily after opening of L3 doors. ALICE 2011-12 winter shutdown schedule - A.Tauro
