Means Detector Services (TS/LEA/DES) Gas distribution and supply • One full time CERN staff (Andre Castel) • Two FTE on industrial service contract (FSU) • Section leader (part time) History: The gas distribution and supply was a service transferred from the AB-department in 2000 and was sponsored by AB (alone) until 2005.

Consumption: LHC vs. Non-LHC Gas distribution and supply LEAF 14.03.2008/M.Wilhelmsson *December not included
Perspective (subjective analysis..) Gas distribution and supply Consumption: LHC: The trend for 2008 is maintained high as all the LHC sites are in operation; Some gas consumption might go down when going in re-circulation mode. Test areas (ISR) are decreasing in consumption. Non-LHC: No information available for any significant change. Manpower: It would be difficult to run the system with significantly less manpower than today. Daily visits are required for operation & safety; however monitoring system will ease the overview (work in progress) Small saving with a “forfait” from the FSU contractor. Non-LHC sites are ageing and will need renovation fairly soon We have a weak point in the absence of a on-call duty. (too expensive… ?) LEAF 14.03.2008/M.Wilhelmsson
