TC Meeting Plans for the next technical stop5 LHC technical stop 30 th Aug – 2 nd Sep Cavern interventions ADA: connect and power-up detector (ADI ) TRD: access to L3 for power line investigation (ADI ) TOF: replacement of two DC-DC converters (ADI ) HMPID: replacement pneumatic valve EMCal: check LTU problem (ADI ) PHOS: inspect condensation coming from cooling pipe PHOS #3 (ADI ) Muon Trigger: Open one half plane outside and access the FEE on the top RPC. Need scaffolding. (ADI ) Muon Tracker: (ADI ) - Upgrade of firmware/software on Crocus - Upgrade of firmware/software on Trigger dispatcher. –Need ladder or scaffolding TPC: Maintenance electronic (ADI )

LHC technical stop 30 th Aug – 2 nd Sep Cavern interventions SDD: cooling system check (ADI ) Trigger – CTP: access in area C To: acces necessary RAMSES: (N.Rousset): intervention on PAXL2451, PMIL2502 and PMIL2511 (ADI ) CV: study routing of new PMD ventilation pipes (ADI ) ASN: cleaning toilettes UX-25(ADI ) Dépannage éclairage Zone C (ADI ) Designers access (ADI ) TC Meeting Plans for the next technical stop6

TC Meeting Plans for the next technical stop7 DAQ off on Monday 30 th for upgrade DCS: HLT: CV (D.Piednoir): –Replacement wheel on redundant pump (#1), iced water circuit (PM). Should not cause any water stoppage LHC technical stop 30 th Aug – 2 nd Sep System upgrades

TC Meeting Plans for the next technical stop8 LHC technical stop 30 th Aug – 2 nd Sep CV/DETCOOL Interventions – J.Botelho Direito and P.Bonneau SSD/SDD: replacement ALICAT supply-pressure regulator S2 (31 st Aug) HMPID: check level transmitter (1 st Sep) SPD (ADI ) (31 st Aug - or 30 th if possible): –Test redundant pump –Inspection compressor –Modification PLC program: Remove automatic switch-over to the redundant pump in case of alarm Implement remote control of compressor and pump Run interlock from the detector The station will be automatically interlocked in case of alarm and the reset will be possible only after the detector operator will have removed the interlock. This will avoid unexpected restart: CV will be able to reset the cooling station only after the formal agreement from the detector operator on duty

TC Meeting Plans for the next technical stop9 Peter: –TOF access baby-frame –Remove TOF crate protection (top baby-frame) Didier: –Repair lock L3 door Frederick: –Humidity/temperature sensors L3 (both injection and extraction) – Visula check of racks in cavern and water leak system control Philippe: –Cabling 4 temperature sensors L3 jacket UW to MCR (SPIE) –Install new lights inside L3 Transport team –Reload nacelles batteries LHC technical stop 30 th Aug – 2 nd Sep Cavern interventions: Alice technicians (ADI ) (ADI ) (ADI )
