ALICE gas systems meeting Outline Introduction Review usage of ALICE gas M&O 2013 Review achievements during 2013 Agree/Review activities and schedule for 2014 Outline R. Guida, A. Wasem PH-DT-DI Gas
PH-DT-DI Gas Service Team • 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.

PH-DT-DI Gas Service Team First contact persons for all issues related to ALICE gas systems during working hours is in charge of: -standard operation -standard maintenance/small modifications -daily check of all systems ALICE A. Wasem 16-0943 ALICE experiment and Gas Service Team If Albin is 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) R. Guida, A. Wasem PH-DT-DI Gas
Gas Service working team • 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 ALICE 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 R. Guida, A. Wasem PH-DT-DI Gas
PH-DT-DI Gas Service Team • 2013 activities can be divided into three main sectors: • Standard maintenance of gas systems for the LHC experiments • LS1 consolidation program for the LHC experiments • Not LHC experiments/support to users • Standard maintenance andLS1 consolidation programconstitute the main field of activity • Not LHC experiments and support to users represent about 20% of the activities LS1 – 2013: Overview R. Guida, A. Wasem PH-DT-DI Gas
Review usage of ALICE gas M&O 2013 • ALICE contribution to M&O budget for gas systems: • 130+ 28 (2013-LS1 consolidation) kCHF • Total 158 kCHF On-call service: ALICE gas M&O 2013: on-call • Analysis (TRD) • Gas supply high flow alarm (Ar, CO2, N2) • Power supply (24 V) • Pressure regulation valve (TPC) • Pump (TPC) • Purifier (TRD) • Xerecuperation (TRD) • Gas supply not ready (EN-MEF) Xe, R134a, SF6, Ar • Infrastructure (GS-ASE) GS intervention, Ar-H2 • Software (EN-ICE) Communication, TPC R. Guida, A. Wasem PH-DT-DI Gas
Review usage of ALICE gas M&O 2013 On-call service summary On average only 1.5 h/year/system of downtime (power-cuts and outside events excluded) Intervention triggered by: ALICE gas M&O 2013: on-call • Intervention are: • Equally distributed between experiments • Decreasing with time R.

Software upgrade Main responsible: Steven Pavis • EN-ICE ispreparing the migration to a new software version (CPC6 & more). • The migration requires to (~) completely rewrite the code (PLC+PVSS): • Preparation phase needed to definestrategy and milestons • Define modules, test logic, … • Validation of one/twogassystemscoveringalmost all functionalities • Deployment on one experiment (all detectors) • Deployment on all the experiments • A completecommissioningwillberequired (same as itwasdoneat the first start-up of the gassystems) • About one-twoweek of stop/instability for each detector • ActivitiyscheduledfromJanuary to April 2014 • Resolveremaining bugs without long stop of gassystems - September-October 2014 Software upgrade R.
