Strategy

  1. Finish remaining kinematic points
  2. Minimize risk:
    1. Finish full 6deg. dataset first to avoid rotation issues
    2. Next get partial dataset for last kinematic points
    3. Ensure we have Al Dummy for each setting by front-loading them at each kinematic change
    4. Aim to finish by Saturday, leaving buffer for contingencies or opportunistic revisiting of other kinematic points

Detailed Run Plan for Wednesday 2018/10/17

Wednesday OWL

  1. Same setting and target as previous shift
    1. Setting: Q2=5.5, W=3.02, x=0.4, θSHMS=6.49
    2. Target: LH2
  2. Desired beam current: 45µA
    1. Do NOT run at higher beam current (will kill tracking efficiency)
    2. Ensure PS1 (SHMS-3-4) is giving pre-scaled rates close to 100Hz
    3. Ensure PS3 (HMS ELREAL) is giving pre-scaled rates close to 100Hz
    4. Ensure PS5 = 0 (This is the physics trigger!)
    5. Make a log entry if changing pre-scalers!
  3. Try to take 1 hour runs
