General information
LHC-TS2: from Mon Sept 18th at 6:00 AM to Wed Sept 20th at 17:00
Planning:
RP check: Mon 8:30 - 9:00  Adam
Keep both magnets ON until Mon 9:00 AM (CTP B field measurement)
Access: from Mon at 9:00 to Wed 16:00
Access mode: automatic restricted (with token)

4. TS2 preparatory meeting
Detector activities 1/3
TPC:
Fix partition C10 RP4
Exchange one Wiener LV PS
Check netgear switches
Measure some distances on TPC A and C side
TPC (laser): Tue PM and Wed
Diagnose and fix problem with Laser 2. I do not know what the problem is, so I can not be more specific. We will need to run the laser if we can, but the work will be limited to the laser hut
Alignment of Laser 1 - in order to possibly improve the amount of laser light in the TPC. This will take 1-2 hours where we will shoot into the TPC. With all pipes in place, this should not interfere with other work concerting safety.
TPCU: install new IROC (Miniframe) + displace RADMON (with Arturo)
TRD:
Manual power-cycle of PSU of TRD, test TRD CRU
15/9/17
TS2 preparatory meeting

5. TS2 preparatory meeting
Detector activities 2/3
EMC/DCA:
Replace ~15 FECs that we initially planed to do during ~5 days (when the TS2 was not shortened) + to replace 1 TRU that broke recently . 
Would be good if we could get access during all possible slots (or as many slots as possible).
ITS:
SDD: replace a couple of faulty LV boards with spares, in order to send them to be repaired. Visual inspection of the SDD cooling plant.
SSD: access to SSD electronics and cooling verification
MCH:
Fix some bus patches in ST2
We will also profit of the TS2 to look better for SOLAR crates, LVPS …for the future upgrade
MTG:
Inspection leaky chamber (need nacelle, O-side) – Mon AM from 9:00 to 10:00
Check FEE in MT11-Inside, need nacelle whole Monday PM (start at 14:00)
15/9/17
TS2 preparatory meeting

6. TS2 preparatory meeting
Detector activities 3/3
T0:
Access to C34-C33 for investigation problem with laser system and T0 electronics.
Access to FIT-A detector prototype (T0 upgrade) - miniframe
TOF: check connections in crate 7 (SM01, C-side) and check cooling pipes in SM08, C-side.
PHOS: reconnection of TRU card
Work will be performed inside the L3 magnet, in the C-side area rack C05, in racks A16, A17with PHOS and CPV low-voltage power supplies, in the PHOS cooling plant at A-side
ACORDE: (3 hours max, anytime)
Basic maintenance to Main Electronics
AD: (2 days, starting Monday at 9:30 AM)
Rerouting of HV cables on the detector side, remounting of HV connectors after adjusting cable length. Need nacelle.
Complete the clean up in CR4, remounting connector after adjusting cable length.
Re-check light leaks on C-Side
15/9/17
TS2 preparatory meeting

EN-CV
SPD: leak detection
HMPID: -
TRD: check of the flowmeter on screen side (transparent)
SSD/SDD: filling + check of the differential pressure transmitter on the mixed water side (transparent)
TOF/PHOS: check of the water treatment (transparent)
TPC FEEC & rod: -
RP analysis foreseen only on TOF/PHOS

9. TS2 preparatory meeting
DCS
Monday morning we will do the usual backup of all WinCC projects. All projects will be stopped and restarted. This implies that most of the morning DCS will not be available. We do not plan to install any patches or upgrades. We will wait to start the intervention until the magnets are down.
Then, as usual, we suggest Run Coordination to reserve some time to make a full cycle (supersafe - safe - ready - safe) with all detectors before first beam; just to avoid any bad surprises.
