No primary water from 12/1 (PM) to 21/1 CR1-2-3, the Wiener PS and detector cooling plants affected (plants can RUN, but no cooling power). Part of DCS will keep running Maintenance on cooling plants. Replacement of pneumatic actuators for TOF/TRD/TPC plants + TOF/PHOS flowmeter. CP will be stopped during maintenance ALICE planning meeting

  27. Maintenance ventilation units UX25, Muon TRK-TRG UX25, Muon TRK-TRG 17 12 SG2 L3 ALICE planning meeting

  28. Safety and electrical systems PX24 fire detect. 20 Evacuation SNIFFER mainten. UX25 fire detect. + red phones UPS UPS DSS Auto-transfert Evacuation Evacuation Early morning/late evening (tbc) UPS AUG DSO ALICE planning meeting

  29. Safety and electrical systemsImpact on ALICE • EN/EL: interruption on auto-transfert network (9/12 from 07:00 till 07:05): • All 'normal power‘ will be cut for 5 minutes: wall outlets, non-UPS in the ACR, SXL2, non-UPS power for the cooling plants, gas systems • It will not affect the 'machine network‘ (all racks will remain powered (part of the 'EXD', machine, network) • This network also provides the power to the UPSes, so they will run on battery for the time of this cut • See https://edms.cern.ch/file/1106913/1/ENNC_2010_196.pdf • EN/EL: AUG Test (20/1) (Arrêt Urgence General – General Emergency Stop) • Major electrical perturbation. Also ACR affected • DSS modification (13/1) • Will stop the full DSS, trigger all interlocks, including stopping power to all racks • LHC evacuation tests (7/12 after 18:00 and 24/12 tbc) • no access UX25 ALICE planning meeting

  30. DAQ upgrade plans • 21st Dec PM till the 04th Jan included • The DAQ will be OFF during the CERN closure. • The ACR PCs will be left ON to give access to the DCS for the detectors teams who need it. • 5th to the 11th of January included • DAQ restarted on the first working day for 1 week. The DAQ will be switched ON with the present version of all software. Allow a quick commissioning after the installation of new detector modules or the intervention on existing detectors. • 12th to the 23rd Jan included • The DAQ will be OFF during the cooling interruption at P2. • DAQ renovated (see TB December) • 24th January • The DAQ will be ON again. It will run under SLC5 64 bits unless there would be an unexpected key problem. • The electronic logbook will remain available during the whole period. When the DAQ will be OFF, it will be running in the DAQ lab in Meyrin. There will be a few hours of interruption to switch from P2 to Meyrin and back. ALICE planning meeting Pierre/Uli

  31. DCS plans Baseline: DCS will be operational all times where technically possible With ‘best effort’ support With access restrictions during CERN End-of-Year closure (22/12 – 4/1) Many activities and upgrades are planned Will be coordinated with individual detectors to minimise impact For central systems, as much as possible in shadow of other perturbations (e.g. cooling stop) Perturbations (e.g. for reboots etc.) cannot be excluded Detectors are invited to communicate ‘critical periods’, with services needed Will try to cater for detector needs as much as possible Known perturbations: Tue 7/12 10:00 – 12:00, interruptions of the GPN link to/from P2 Upgrade of router, test impact on ALICE Wk50 (13-17/12) – major updates to all PC (many perturbations to be expected) 12/1 – 21/1 (cooling stop), only minimal central services. All detector DCS switched off, except for special requests and if cooling power allows More detailed planning at weekly and daily meetings 26/11/10 ALICE planning meeting ALICE planning meeting 31 André / Peter

  32. Magnet control upgrade • Wk 49: nous devons intervenir dans la MCR pour: • changement des alimentations 24V et 48 V des systèmes MSS et MCR (préventif) • changement des modules convertisseurs PT100 des hots points du Solénoïde (correctif suite à deux incidents ayant entrainés l'arrêt du Solénoïde) et en UX25, comme Philippe Bouvier l'a déjà signalé: • recâblage des AU du dipôle et du Solénoïde • signalisation du champ magnétique du dipôle et du Solénoïde • Nous étudions toujours une solution pour le monitoring des températures du Solénoïde. • L'arrêt de fin d'année va permettre de faire une meilleure approche de ce qui est existant en UX25. • En ce qui concerne l'alimentation électrique de la MCR, nous dépendons actuellement d'une seule source de courant sous UPS avec secours diesel. • Afin d'établir une redondance pour l'alimentation de la MCR je souhaiterais installer une seconde source d'alimentation sous UPS. • Je sais qu'une étude est faite à ALICE pour augmenter la puissance des UPS existants en 2012. • Je souhaiterais que cette demande soit incluse pour le calcul de puissance des nouveaux UPS (besoin pour la MCR: 16A en monophasé) ALICE planning meeting Pascal

  33. VIP visits – wk 49 • Portuguese Press visit to CERN (7/12 14:00 to 15:00). 10 persons ALICE planning meeting

  34. AOB • SLIMOS shifts still missing in wks 49-50 and 4-5 ALICE planning meeting
