Reminder about safety courses

• From now onwards the « CERN - Beam Facilities » will be needed for access requests to ALI-UX and ALI UX-GUI.

• All person including those presently having access to ALI-UX and ALI UX-GUI will lose the access right, if they have not completed successfully the « CERN - Beam Facilities » e-learning before the final migration date. Therefore please take a moment to complete the « CERN - Beam Facilities » e-learning course at http://sir.cern.ch as soon as possible.

Not yet final


TPC other• Laser maintenance

– Preventive maintenance of lasers. Check performance and status of flash lamps. If necessary, replace flash lamp(s), tune energies and alignment.

– For alignment, it is necessary to shoot laser into the TPC. This will be coordinated with the TPC team at a time when nobody is working on the TPC.

• Gas (PH-DT): work on TPC pump and frequency variator (CR5)

03/06/15


ITS• Visual inspection of the ITS cooling plants and power supply racks

• SPD cooling work– RP check (Mon)– Filling tank

Thursday

TS1 preparatory meeting 1303/06/15

CV-DC to put in SDBY the TPC FEE and SPD plants on Monday early morning (7:00 AM)


TRD/TOF• TRD: Ethernet + optical fibers checks inside L3

– Thursday or Friday during the day

• TOF: replacement TDCs• Overnight or Thursday or Friday during the day• Andrea to see with Bologna people and let us know

03/06/15


EMCal/DCal

• Understand and fix why EMCAL (SRU) voltages trip at configuring EMCAL STU

• Fix LED box of one of EMCAL SMs. C-side top (SMC1)• Reprogramming of TRUs• Swapping EMCAL STU DDLs• Replacing (about 10) FECs of EMCAL and DCAL• Connecting DCAL STU back to PHOS power supply

• EMCal: work overnight Mon-Wed + during day Thu-Fri• DCal: anytime, must be coordinated with PHOS

03/06/15


V0

• Access for V0 FEE firmware upgrade (rack C04)

03/06/15


MCH• Replace gas pipes on stations 4 and 5 (at the bottom off the chambers): no need to

open the chambers• Check LV connection stability on CH8R G7 (at the LVPS, filter box levels…): no need

to open the chambers• Visual check of mechanics on station 1

03/06/15


MTR• 3 gas gaps (MT11-2; MT21-6; MT12-line1) OUTSIDE to be checked/repaired/changed

• Nacelle needed (EDH request #6037399 from low beta platform to UX25 side C level 1 outside).

• Since there is not access through PX24, the gas gaps are to be carried down with the LHC elevator at P2 (LHC-TNL access) and the passage through the UP25 chicane (YCAMM01) is needed (gas gap is approx. 2,7 m long)– Answer from LHC coordination: the best is to perform the activity on Tuesday 16th. On

Wednesday 17th the UP25 MAD is in maintenance and a patrol is scheduled on Wednesday afternoon.

• The cables on RPCs are first disconnected; then the gas gap is lowered using dedicated electrical hoist (while guided by persons on the nacelle); the gas gap is then checked in UX25 side C level 1, eventually repaired or changed with new one. The gas gaps are then remounted on the Trigger mechanical frame and reconnected

• Installation/test of USB blaters and micro-PCs (upper gangways, close to muon trigger racks) for the remote programming of the 16 Regional card firmware (C. Renard, JL Beney). In coordination with Andre Augustinus et al.

• Minor FE electronics maintenance (Ph. Rosnet)03/06/15


DAQ/detectors activities• TPC: swap a pairs of links (RCU 0 and 1) inside the module of TPC A14 placed in the

Mini-Frame patch-panel. This activity will be coordinated with the RCU replacement works. The work will be made by Joan with the help of Filippo for what concern the coordination with TPC activity.– Small interference with TPC A-side work– Will be done on Tuesday

• EMCal: swap the two fibers of EMCAL STU in the module of patch-panel located in L3, to have the correct polarities of fibers in CR1 (Martin and Filippo)– Will be done on Thursday

• PHOS: inspection and repair of the PHOS STU DDL fiber inside L3 (max. 1 hour)– Will be done on Thursday

03/06/15


Other interventions• TE-VSC: close/open manual valve inside miniframe

– Close: Monday morning at 8:00 AM– Open: Friday afternoon after 14:00

• EN-HE: reinstall/remove crane electronics– Reinstall: Monday morning– Remove: Friday 14:00

• GS-ASE:– Gas detection maintenance (SG2, CR5 and UX25) transparent– UP25 MAD maintenance Wed. Will drop the patrol

• IT-CS:– TETRAPOL measurements (A TETRAPOL radio will be used to measure signal strength and other

parameters. Nothing will be physically installed or modified in the tunnel/experiment)– IT-CS: cut GSM network. There will be a max. 10 min cut of the GSM network at 7h30 on the Monday

morning, and a second cut after their tests, during the afternoon. For the 2nd cut they will call Andre.

03/06/15


Other interventions• EN-CV-OP:

– Intervention EN-CV (sand filter) in UW25– ITS ventilation unit – test control (1/2 day) Monday PM– SG ventilation SW update will stop the flammable gases, date tbd

• EN-EL and EN-CV:– Stop circuit breaker ESD1/2E, scheduled on Tuesday morning – Will affect cavern/magnet ventilation and flammable gases (2 x 30” stops at 8:30 and

11:00)

• EN-EL:– Maintenance emergency lights UX25

03/06/15


DCS

• Monday morning (09h - 13h) for maintenance. The major activities will be:– Installation of new file servers (will bring additional

redundancy)– Restart of all WinCC projects

• We do not plan any patches or other updates to the software. The implication is that DCS will be unavailable during (most of) that morning. We will assure the availability for the rest of the TS (notably for the TPC tests).

03/06/15


CTP

• Change a CTP VME L0 board• Intervention in one VME crate

• This would mean 2 workers at C-side racks for ~ 4 hours, preferably on Monday

03/06/15


P2 technicians activities

• Replace lights on Monday morning (Philippe)• Installation of platform on Monday morning (Yannick)• Install 2 chairs + 1 table in the watcher corner on Monday

morning (Transport)• Install fence above L3 busbar (SPIE, Mon)

• SPIE:– Connection new racks (C19,C33,C34) in C-area (smoke detection,

Thermoswitch, ELMB)– Cabling secondary network outlets for Netgear redundancy

• Installation beampipe/AD thermocouple readout PLC in rack C29

03/06/15


Visits

• Tuesday 16 June in the morning (DK Council members)– Protocol office asks us whether we can take care of it

Modus operandi (1)On the TPC sectors:1. Open sectors and secure blue covers2. Drain RCU cooling loop3. Remove mounting bars4. Disconnect cooling pipes, fibers, cables

from RCU1 (DDL stays connected for RP0 and 1)

5. Protect fibers6. Remove RCU1 and backplanes7. Bring material outside magnet8. Install new backplanes9. Receive new RCU2 boards with cooling

plates. Check position label10. Install new RCU211. Cable and connect12. Put back alu bar13. Fast connectivity test (DCS,

DDL2, control bus, data bus)14. Close sector

35

Modus operandi (2)

In parallel outside1. Receive innermost mounting bars, RCU1 and

backplanes2. Store old backplanes3. Modify innermost mounting bars in workshop4. Remove top cooling plate from RCU1 boards (4

screws)5. Mount these cooling plates on RCU2 boards6. Add label (Position!)
