16

DCS

Week 49• Dec. 8 morning: shutdown all DCS for UPS repair; restart a.s.a.p. (afternoon)

– Profit from DCS stop to make backup !• Start (hardware) installation of new DCS cluster

Week 50• Dec. 12–14: Operating system and PVSS upgrade

schedule - A.Tauro17

TPC

• Take out capacitors on all A/C ROC


18

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.


19

Removal of FMD2 box


Present situation Situation without the box. The blue cable tray should stay in

place

Cable ends

2/12/11 20

Removal of FMD2 box

• Who: Borge

• What:

The cables from the detector are disconnected and secured. The box and the patch panels are unscrewed and dismounted. Then the patch-panel and the cables should be moved aside and secured. Uncertain where to put the cable bundle and patch panels – very stiff bundle.

• When: 8th December morning


2/12/11 21

Removal of SSD-SPD boxes


Present situation. The plate restricts the TPC access

SSD box

SPD box

Situation without the SSD box

Situation without the SSD and SPD boxes. Now the plate can be

easily removed

Plate

2/12/11 22

Removal of SSD-SPD boxes

• Who:– SSD: Ton– SPD: Michel Morel

• What:– The SPD box is removed from the MNF. The only risk is to damage the

fibers.– The SSD box is also removed from the MNF, and the cable trays from

PP1 should be opened. The box cannot be taken away, therefore the cable from the detector + box will be displaced and attached to the beampipe table for some days

– The plate is easily removable (4 screws), and this will be done by Yannick or Pieter


2/12/11 23

Removal of V0-FMD1

• Who: Yannick, Pieter, Werner and Borge

• What: disconnection and displacement of V0-FMD1. The detector will be parked inside the MNF for some days. The removal is a complex but known operation. The main risks for the equipment are related to the beampipe and the naked silicon sensors of FMD1. Both will need temporary protection once the detector is moved out,


2/12/11 24

Schedule

• 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 1/2 days)– Fri-Sat: move back and test V0-FMD1

• Week 6:– Mon 6/2: survey of V0-FMD1


2/12/11 25

PMD

• Week 3 or 4: PMD moves to Parking Position• Week 4 - 6: PMD Maintenance

– Replacing some of the modules which are having problem– Replacing some of the FEE Chains– Need cooling for the DAQ (Crocus) so that we can check the health of

the modules and FEE chains.• Week 7 (after 17:00) and 8: Access to Crocus Crate for DAQ• Week 9 -10: PMD Moves back to Final Position


26

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.


27

TRD

• 3 supermodules installation, cabling, commissioning (L3 access, A & C sides etc)– Arrival at CERN of Bernd & Co on 2nd Jan. around 12:00 AM– Insertion sequence: 6-2-3– Possible to have transport on Sun.8th Jan?

• C19 power installation -> we will ask DCS• C16-19 Netgear switch rearrangement• I08/O08 Netgear switch rearrangement• DAQ upgrade (discussion on going between Joerg and DAQ group)• Pretrigger backup PSU installation and LV cable rearrangements (I/O rack and C-side

in L3)• BKF LV protection panel replacement (C-side in L3)• Colling valves replacement for 10 sectors, C side (if necessary, ask Ana to judge) (C-

side in L3)• Moving back pressure sensors from TPC TS to TRD (C-side in L3)• GTU optical fiber installation (Stefan) (C16,17,18 racks)• CR4 HV rearrangement for new super-modules


28

EMC

• New rotator nose: installation and check end Dec/beginning Jan– Depending on delivery of nose to P2

• Arrival at CERN of Manoel & Co on 22nd Jan.


29
