Point 1 TS3 ZDC activities:

• ZDC transfer to the LHC tunnel and installation • Work in USA15 and check operation of HV, NIM modules, TDAQ partition• Cabling 4 big PMTs in ZDC sector 12 - 81 • Connect HV, analog cables, NIM crate • Connect laser• Test connectivity• Connect pixel HAD1 sector 12 - 81 • ZDC removed during YETS W51

TREX 5th November, 2015 4

Point 1 TS3

AFP RP stations:• Installation of secondary vacuum pumps and + crate,

connection to mains (LHC UPS) in RR17• Compressed air infrastructure in the tunnel – VIC only • Installation of short missing cable trays at both ATLAS arms

• cable tray on the floor between stations and patch panel (205-217m, vertical cable tray behind QRL)

• short cable tray at RR17/RR13 entry• floor opening at RR17/13 (cable passage) ?• short cable tray in UJ17/UJ13

• Mark beam line position and start and end points of stations on the tunnel floor (preparation of drilling)

TREX 5th November, 2015 5

Point 1 YETS AFP RP stations:

• Install detectors @ C6R1 during YETS• The works involve:

• Cabling • Trigger (1R, 1L) and control cables (1R ?)• Cabling campaign for control between W1 and W2 1wk allocated• Common visit scheduled during TS3• Safety requirements:

• Method statement for the work to be carried out.• Erection and verification of mobile tower scaffolding, and its proper use.• Mobile elevated working platforms if they will be used• Safety at CERN• Electrical Awareness HO/BO• Biocell training • Masks and all other individual protection• Personnel Dosimeter

• Drilling for the supports• Vacuum chamber modification between Q5 and Q6 (1R)• Equipment commissioning from surface

TREX 5th November, 2015 6

Point 1 YETS

New Water Cooled Cables for ALFA• One extra DC water-cooled cable will be added for Q4.L1 and Q4.R1

(RR13, RR17)

TREX 5th November, 2015 7

Point 5 TS3 ZDC activities:

• Removal of absorber bars from TANs and installation of ZDCs;• Connection of HV and readout cables;• Test of the functionality of the calorimeter.• ZDC removed during YETS W51

Crane in Operation in LSS5

TREX 5th November, 2015 8

Point 5 TS3TOTEM timing detector sector 45:

1. Exchange detector package for RP 220m near vertical top:• stop cooling• open cooling circuit• stop vacuum pump - ventilate the RP 220m near vertical top • remove present detector package from Roman Pot• Measuring of thin window gap with LASER • install new detector package with Diamond timing detector in Roman

Pot• reconnect vacuum -> leak test• reconnect cooling -> cooling test

2. HV connectors and HV lines• install HV connectors on HV cables in tunnel• install (attach) two little racks to the RP unit 220m near• install SAMPIC board and PC in this rack with timing electronic

components

TREX 5th November, 2015 9

TOTEM timing detector sector 45 & 56 (ECR under preparation):• Installation of TOTEM clock distribution and timing detectors starting on TS3 and

progressively on YETS & TSx

CMS TOTEM PPS timing & tracking sector 45 & 56 (ECR under preparation):• Installation of coax cable for clock distribution Open issue • Installation of detector packages for both tracking and timing starting on YETS

and progressively on TSx• Main services existing, but new installation of small racks & patch panels

LHC beam line for TOTEM:• Depending on pressure development the installation of a pump between Q5 and

first Roman Pot unit 210 near might be necessary (sector 45 & 56)

Point 5 YETS

TREX 5th November, 2015 10

Point 8 TS3 Shower Counters:

• Calibration measurements on LHCb forward shower counter stations.• Both sides RB84 and RB86• IT 8L & 8R will be empty from Tuesday to Thursday

TREX 5th November, 2015 11

Point 8 TS3

Scintillating Fibre module:• Installation of scintillating fibre module.• RB84 side• IT 8L will be empty from Tuesday to Thursday

Placement of the fibre module on the ECAL table and the shielding wall of RB

Conclusions

TS3Requests from experiments are well integrated in the TS3 Schedule and there are no constraints.

YETS- Activities related to ATLAS AFP and CMS TOTEM PPS need to be

carefully planned due to potential co-activity issue with 5th axis collimators restoring.

- Not all activities concerning TOTEM timing detector and CMS TOTEM timing & tracking are announced, so the potential co-activities issues are not yet evaluated (drum passage, …)
