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)

• Wk 52 – Wk 01– Only ‘best effort’ support during CERN closure

• Wk 02– Wed 12/01 – (cooling intervention) shutdown of detector systems

• except special requests, within limits of cooling power

• Installation sequence: 16 → 15 → 11 (or 16 → 11 → 15)

• 2 technicians (Philippe and Didier) + Survey (Nail from 6/12) + TC permanently at P2

• Connection done right after installation

• Survey:– Space-frame deformations and displacement of beampipe (flange), miniframe

and TPC feet. Before-after each insertion– Modules (2 points/SM on 4/7 SM) in wk 50– Modules (3 points/SM on 10/10 SM) after EMCal (wk 3)


TRD• Week 49:

– LV Wiener ~70 PSU Back-Plane modifications (to improve mechanical stability, same as TPC applied already)

– Netgear switches replacements (1 day)– LV line fixation: installation of improved patch panels on front of module (C-side)

and replacing cables

• Repair pretrigger (A-side, below PMD) – after 20/12

• Week 1:– Finalizing connections, start commissioning

• Week 2:– Stable running with cosmics

• 3 to 4 weeks in January or February:– Stable running with cosmics for alignment and with Krypton for gain calibrations

(to be still discussed)


TPC

• Recover all water inside cooling plant (week 50)• Replacement of 15 damaged FECs (equally distributed A-C sides)

– ~3 days per FEC. Therefore, we would like to use all available time slots where access to the L3 is possible

– At the end of this activity we will need a period of about 2 weeks where all aforesaid systems are available for final verification, and access to the TPC in case something is not working correctly.

• Kr data taking at the end of the shutdown (1 week)


TPCReplacement of the laser

• Start the dismantling of the Spectron laser (week 50, Th-Sat after 18:00):– dismount back wall of laser hut (help of P2 technician)– stop cooling water (help of P2 technician)– prepare new water connection (electrical power should be OK)

• Install new Ekspla laser (week 1):– remove old laser and install new (use crane to transport laser)– connect cooling water (help of P2 technician)– reinstall back wall (maybe after cutting a hole in it)

• Testing and alignment of new laser (week 2):– possibility to run laser behind closed doors (inside hut)– maybe install laser tube temporarily and shoot into TPC whenever– compatible with other installation work

• Possible further testing and adjustment (week 3)

Borge


ACORDE

• Check some ACORDE modules (PMTs optical conections, connectors, etc) above the magnet

• The plan is to start this activities after the second week of January 2011


Other activities

• SPIE + CV: refurbishment ITS dehumidifier in CR – February– New unit at P2 in January– Repair leak (replace leaking part – transport needed)– Recirculation air– Add flowmeter (connect to ELMB: Frederick)

• EN-EL (T.Bourrel): motorize L3-Dipole-Miniframe circuit breaker.– VIC 16/12 10:30

• SPIE: cabling UX25-CR4 – 17/1

• New magnet emergency buttons + flashing lights L3 and dipole

• Frederick: humidity sensor L3 ventilation (extraction) + redo CTP connectors

• Intervention on cavern lift– One day stop – no access to UX25. To be scheduled


Other activities

• Google propose to produce a custom Streetview application for CERN showing both outside and underground areas

– Visit Tuesday 21 December at 16:15

• Philippe: replace rack filters during cooling stop. Install temporary line PHOS cooling (PS rack and crystal cooling plant)


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)
