neutral gases: tot 9 lines ▫ Ar, CO2, N2, He, SF6, CF4 and 3 spare pipes▫ Distribution panels: 4 gas service area + 1 preparation zone

flammable gases or gases with very low vapour pressure: tot 6 lines▫ iC4H10, CH4, Ar/H2(optional), C2H2F4 and 2 spares. Lines and room heated.▫ Distribution panels: 1 gas service area (flammable gases)

1 normal exhaust 1 exhaust for potentially flammable mixtures

At full capacity the gas mixing zone will contain ▫ 6 mixing racks▫ 3 closed loop gas systems ▫ 2 analysis racks ▫ 1 control rack▫ 5 spare racks

Gas analysis: ▫ 1 O2 and H2O analysis rack (LHC design: automatic

scan between all gas streams selected. ▫ Gas chromatograph will be integrated in the O2-H2O

analysis rack. ▫ 1 Infrared analysis rack for monitoring iC4H10

concentration in cosmic trigger. ▫ Hardwired interlock signal to stop the system will be

send in case problem (DSS)

• Gas mixture distribution: Each distribution panel: 6 supply (outer diameter 8 mm) and 6 return (outer diameter 10 mm).

The gas distribution is divided in:▫ panels for neutral mixtures (type A) ▫ panels for mixtures that might contain flammable gases (type B).

Gas service area ▫ 6 panels type A ▫ 2 panels type B

Irradiation bunker ▫ 6 panels type A ▫ 2 panels type B

Preparation area▫ 3 panels type A ▫ 1 panels type B

Conclusions – start-up version

First version to start-up the facility:

1. 20 distribution panels2. Simplified version of control rack (basic functionality like connection to remote pvss

interface for recording flows, gas systems status, …)3. 2 gas mixing racks for the fixed installations (beam and cosmic trigger setups). Any

additional mixer for users will cost about 15 kCHF (not included in the present list).4. 1 IR analysis rack (needed to operate cosmic trigger gas system). 5. 1 analysis rack (O2+H2O+ gas chromatograph). 6. 1 closed loop gas system.

Gas systems – future upgrades

Many possibilities for future upgrades to be discussed with users for resources:1. Upgrade control rack for more units (mixers, analysis, re-circulation systems, … )2. Additional IR analysis rack for second mixer using flammable gas3. 3 mixers for users (15 kCHF each)4. 3 new gas recirculation systems for users5. Install more distribution panels (?)
