  1. RPC GAS SYSTEM • Commercial grade Gas :Do in-situ purification • Regeneration must :Get back ~90% • Fixed pressure control room: pressure at all points in room ~ 1mm (weather maker) • Mixtures:3 Gas system (Each Module) + 1 Spare • Safety : • Level 1:RPC Safe :Level 2:People working and Level 3 : Everything • Main Gas Tetrafluoroethane (High density leading to ~60 primary electron-ion pair

  2. CERN Recirculation

  3. Fractional Distillation

  4. Gas Collection

  5. Gas Distribution • Mixed Gas

  6. Gas Requirement • For one Module : 64 RPC/Layer X140 Layer=8960~9K RPC Volume=200 X200X0.2=8000cc Total Gas = 8L/day (One volume/Day) 8000/24=333.33/60~=5.5 cc/min At least we need ~10 SCCM 10 X 9K== 90L/Min If 20% fresh gas ~18L/min=1080L/Hr=25920L/Day 1kg==220lts=25920/220=1080Kgs/day

  7. Gas Requirement Avalanche Mode : 95 % Freon 1kg Freon  220 L 8640L/Day 8640/220=39.27=~40Kg/day 1 cylinder k-size is 27.7kg then =~1.5 Cylin/day

  8. 1. CLOSED LOOP : Remove OF Water Vapour,O2halogens and silicons produced 2. TWO (ACTIVATED MOL. SIEVE + Copper WATER AND O2 ) 3. REGENERATION :HEATING 180deg. +FLUSHING WITH Ar + H2 (935/7%) 4. LEAK RATE OF CHAMBERO2 Removal PURIFIER

  9. RPC Tray
