===== MAMI needs optimization =====
  - Beam off -> ELOG entry "beam off, MAMI optimization, maybe reason"
  - Detector HV off and afterwards pre-HV off ([[prima_control:how_to_ramp_hv|How to ramp the high voltage]])
  - Change target to "Empty" ([[prima_control:target_control|Target control]])
  - Now MAMI can start the optimization -> call MAMI
  - when the optimization is finished, normally <1h (call from MAMI): check beam position ([[prima_control:target_control|Target control]])\\
    - change target to luminescent screen (Al203)
    - turn on target camera
    - turn on beam slowly (MAMI) until you see a white spot
    - ask MAMI to center the beam
    - take a picture
    - turn beam off 
  - now you can move to the desired target ([[prima_control:target_control|Target control]])
  - turn HV back on ([[prima_control:how_to_ramp_hv|How to ramp the high voltage]])
  - turn beam on with the desired current -> ELOG entry "beam on, target XY, current XY"
