  1. TC meetingP2 planning wks 10&11 A.Tauro 6-3-2012

  2. Planning wk10 • TPC: • Fix some bad connections between FECs and Readout Chambers • Fix some other issues (non-working pressure and temperature sensors and replace some bad seals in cooling loop 21 for thermal screen) • SPD cooling. Drill SR6 (Tue) • EMC: check electronics • TRD: • Rearrangement (different mounting scheme) of existing Ethernet switches (Racks I08, O08, C19) on Tue afternoon • Check of one LV connection (inside L3, Sec02 C-side) • P2tech: reinstall green fences C-side (Fri) • Muon TRK: • Repair slats on ST3-ST4-ST5 • Move PMD to final position (Mon 14:00, done) + reinstall cooling pipes • Reinstall ADA (Fri, 9:00) • BE-ABP-SU: PMD survey (Tue) + Muon-TRK survey • EN-HE: removal crane electronics (Fri) • EN-CV-BE: start-up and commissioning new ITS dehumidifier (5th Mar, delayed to 12th) + new PMD cooling unit (Tue) • TE-VSC: open manual valve in MNF (Fri) • T0: check electronics (9/3 to 12/3) • ONET: cleaning UX25 cavern (start on Mon from CTP area) • INEO: install 220V sockets in backframe and miniframe (Tue)

  3. Planning wk11 • SSD: air quality measurement • T0: check electronics (Mon) • V0: FW update

  4. L3 cooling (jacket) temperature Switch-off L3 cooling Switch-on L3 cooling

  5. L3 injection/extraction temperatures extraction injection Increase in pulsion temperature (green) due to cooling failures (24.02 and 29.02), otherwise stable Variation in extraction temperature (blue) probably due to heat load inside L3

  6. Ambient temperature, top (A1 and C2) and bottom (A2 and C1) on spaceframe on A and C side
