Change Target

  • Make sure the beam is off! Usually one moves the target only while being on the phone to MAMI.
  • Open a terminal as mezzo on control1
  • Optional: Check the target position with where_target
  • Go to the new position with the appropriate go-command (e.g. go_C12)
  • Check the target position with where_target. The setpoint should be the selected target, and the difference should be small ( < 100 )
