  •  Prepare the hutch for the shift (done 1h before the actual start time)
    •  no gate valve in the trajectory!!!

      •  check in the vacuum windows that no gate valves from the NEH to the MEC hutch are IN (red)
      •  it is ok that the DG2 STP 1 is IN
      •  it is ok that the GL window is IN in MEC
    •   check that all devices in the beamline are in OUT position
      Code Block
      languagepy
      themeRDark
      op.rs()
    •  insert yag3
    •  make sure all GREEN from 'Machine Protection' list
    •  check 'MR1L3' mirror OUT (-6000) position (after XCS)
  •  15 min before the shift begins, call ACR at x2151 to check:
    •  photon energy
    •  nominal pulse energy
    •  nominal pulse duration
    •  beam mode
    •  multiplexing
    •  e-loss scan needed?
  •   when you are beam owner (confirm with ACR), you can start the following:
    •  close DG2 STP 1
    •  open mecpython and use op.rs()
    •  insert YAG0 ([1] op.yag0.insert())
    •  confirm FEL beam is on scale "0"
    •  confirm the shape of the beam is round
    •  insert YAG1 ([1] op.yag1.insert())
    •  insert MR1L4 : check coating for photon energy
    •  confirm on yag0 that the beam is properly deflected on the scale "8 cm"
    •  remove YAG0
    •  remove all Si attenuators ([1] op.SiT(1))
    •  open the pulse picker ([1] op.pulse_picker("open"))
    •  fine tune the pitch of MR1L4 to center the beam on YAG1
    •  insert YAG3 ([1] op.yag3.insert())
    •  remove YAG1
    •  fine tune the pitch of MR1L4 to center the beam on YAG3
  •  once they are done tunning
