4. 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 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

5. 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 and LS1 consolidation program constitute the main field of activity
Not LHC experiments and support to users represent about 20% of the activities

6. Review usage of CMS gas M&O 2013
CMS contribution to M&O budget for gas systems: 157 kCHF
On-call service:
purifiers RPC, CSC
IR RPC SGX5
Supply R134a
CSC broken bubbler
Distribution RPC, CSC, …
Primary Gas Supply monitoring alarm
SX5 and 904 mixers

7. Review usage of CMS 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:
CMS gas M&O 2013: on-call
Intervention are:
Equally distributed between experiments
Decreasing with time 

16. Software upgrade Main responsible: Steven Pavis
EN-ICE is preparing the migration to a new software version (CPC6 & more).
The migration requires to (~) completely rewrite the code (PLC+PVSS):
Preparation phase needed to define strategy and milestons
Define modules, test logic, …
Validation of one/two gas systems covering almost all functionalities
Deployment on one experiment (all detectors)
Deployment on all the experiments
A complete commissioning will be required (same as it was done at the first start-up of the gas systems)
About one-two week of stop/instability for each detector (CSC, DT, RPC, T1, T2, ID flushing, …)
Activitiy scheduled from beg. March to June 2014
Software upgrade
