BLM system

List of BLM Programs

 

BMCF (Combiner)

  1. Manual change of energy using the navigator:
    1. Before any action get, making the action set
    2. blecs EMCR true
    3. blecs BEESE true
    4. blecs BEV 0 to 31 (energy steps from
    5.  

 

 

Beam current transformer (Michael, David)

  1. IP 4  4 units in RA47 (BCTRF) one spare unit one per beam
  2. sytem A for operation, B spare system

  28. auto ranging to be commission

 

BPM: reboot:

/ps/local/Linux/bin/dsc_family BPMLHC blind_reboot

  1. BPM concentrator, needs trigger navigator tool used to set the trigger
    1. cs-ccr-bghtlhc
    2. nonebpmlhcconc
    3. prepulse for capture
  2.
