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.

Pierre/Uli


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

André / Peter


DCS plans (details)• Wk 50

– Mon 13/12 – Fri 17/12 (daytime): SW upgrades and patches to all systems (Operating system and PVSS)

• Delayed/extended due to problems with automatic PVSS upgrade procedure (several manual operations needed)

• Systems unavailable for short (~hrs) periods, frequent reboots

– Support to detectors restarting/testing their systems after upgrades• Detectors shall test functionality as much as possible

• Wk 51– Contingency for system upgrades– Support to detectors restarting/testing their systems after upgrades

• Detectors shall test functionality as much as possible

– Tue 21/12 PM: Limit access to DCS cluster during end-of-year closure• Register with your SRC if you require access (see message Peter 2/12/2010)

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)

GS/ASE: UX25 fire detection maintenance

DAQ: switch off DAQ. The ACR PCs will be left ON to give access to the DCS for the detectors teams who need it

DCS: the access restrictions to the DCS network will be enforced from December 21st towards the end of working hours

Activities:• TRD: install TRD16 + insert TRD15 into rotator• Survey TRD16

– The beampipe (i.e. also ITS and TPC) have moved 0.35mm to the O-side and 0.14mm down during the installation of TRD16. This is consistent with Yannick’s measurements of the spaceframe position with respect to the backframe

• Philippe+Didier: removal ladder BKF• PMD: replacement electronics chains

Week 51 - 21/12 Tuesday
