SM18 RF TF : General PID for 2013
M9 - Service module
Warm pumping unit capacity:
• 6 g/s @ 10 mbar• 12 g/s @ 20 mbar• 18 g/s @ 30 mbar
Very low pressure heater:
32 kW (20 g/s)
- LHC temporary connection with semi rigid bayonets: LHe supply and GHe return, 4.5 K operation, 80 % reused
later.
- Hie-Isolde CMspecial procedures for cool down and warm up, 4.5 K operation + shield cooling at 50 K.Two Venturi flow meters
- CRAB cavity CM operation at T< 2 K, shield maybe at 80 K?Helium guard, Pressure relief devices: SV at 1.8 bara, RD at
2.2 bara
