  • 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.

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 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)

  • 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

  • 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

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

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 

  • 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
