De Menezes (0.5) CMS-TOTEM Andrea D’Auria (0.5) LHCb Patrick Carrie (0.5) Steven Pavis (0.25) Coordination R. Guida FSU team Jonathan Dumollard Abdelmajid Laassiri Benjamin P. Marichy Herve Martinati Ace Ordanov (User) Cedric Landraud (also CMS-CO2) Guillaume Lacroix (also CERN Expo) Gas Service Team mandate:  M&O and upgrades of the gas systems for all the LHC experiments: -preventive and corrective maintenance on 30 gas systems -on-call service all along the year (24/24 7/7) – phone 162516  Construction of gas systems for other experiments at CERN (CLOUD, NA62, LINAC4, …)  General support for test beam and equipment belonging to external users.

Pavis PH-DT-DI Gas3 LHCb experiment and Gas Service Team PH-DT-DI Gas Service Team First contact persons for all issues related to LHCb gas systems during working hours is in charge of: -standard operation -standard maintenance/small modifications -daily check of all systems LHCb Patrick Carrie – Steven Pavis 16-0415 – 16-0929 If Patrick and Steven are on holiday or busy: -during working hours  call directly Roberto (16-2146) -outside working hours  call directly on-call service (16-2516) Outside working hours  call directly on-call service (16-2516)

4. 25/03/2014P. Carrie, R. Guida, S. Pavis PH-DT-DI Gas4 In order to cope with LS1 a significant reinforcement of the team during 2013 was needed: ▫two new users with high experience in the workshop (mechanics and gas systems) ▫many students for short and well defined projects Details:  CERN FTE (and students > 1 year): ▫6.3 FTE: +1.3 wrt 2012  -Ernesto: TTS 50% for gas project  “FSU” (FSU + technical users): ▫5.5 FTE: +1.5 wrt 2012  -Ace: user on ATLAS budget -Andrei: user on ALICE budget  Trainees (student < 1 year) ▫1.9 FTE: +1.8 wrt 2012  -4 trainees (3 from Poland, 1 from Canada) -2 summer students -2 children of staff members Working team Gas Service working team

5. 25/03/2014P. Carrie, R. Guida, S. Pavis PH-DT-DI Gas5 2013 activities can be divided into three main sectors: 1.Standard maintenance of gas systems for the LHC experiments 2.LS1 consolidation program for the LHC experiments 3.Not LHC experiments/support to users LS1 – 2013: Overview PH-DT-DI Gas Service Team  Standard maintenance and LS1 consolidation program constitute the main field of activity  Not LHC experiments and support to users represent about 20% of the activities
