  • Set up beam through Compton chicane (Ciprian, Greg, Yves)

Specific mission

  • Note:

1/ Set up beam through Compton chicane

- Ciprian, Greg and Yves  are tuning the beam through Compton
- Before tune the beam, observe the beam current (how actually we can get tonight but only up to 30uA) - Spoke to Ciprian/Greg/Dave and they gave a specific monitoring instruction (shift crew will post everything). - We will give a try ...

2/ Expect some production runs through Compton

- 15uA with LH2 
- Compton S/B looked great
- Spot++/C12 hole/ Some production runs ! 

3/ Agreement with Hall-D and Talked PD to set up the BCM calibration tomorrow

- Crucial: high beam current 30uA with FC & empty target 

Instruction: DOC1DOC2

- Experts on call (Dave/Julie/Thir/...)
- Calo. HV off

BPM/Spot++ Check

  • After beam lost for considerable time (like beam study, pass change,...)
  • Ask MCC to run 5uA wth carbon hole target and make sure you can see the hole through Spot++
