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)

  • Requirements of customers in M9

  • LHC temporary connection with semi rigid bayonets:

  • LHe supply and GHe return, 4.5 K operation, 80 % reused later.

  • Hie-Isolde CM

  • special 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

  • Functional specs for He distribution in M9 can be found in EDMS:

  • Test schedule in SM18 RF : horizontal bunkers

  • Projects:

  • 1 test @ 4.5K of LHC cryo module . Provisional schedule : 2013

  • 2 tests @ 4.5 K of HIE-Isolde cryomodule. Provisional schedule : 2014

  • 1 test @ 1.8 K of SPL half cryomodule. Provisional schedule : 2014

  • x tests @ 2K of crab cavity CM. Provisional schedule : 2nd half of 2015
