• •  Continue by checking the alignment of the VISAR system
    •  

      Adjust the VISAR Z axis to make sure the image is round and sharp (could be set to the value by using the right equation as well)

      Code Block
      language py theme RDark linenumbers true
      x.visar_z.umvr(50e-6)

    •  

      Alternatively, move the Z value by exactly the hitckness of the ablator + material of interest and add the change in position due to the visar window. To calculate the change use the following command

      Code Block
      language py theme RDark linenumbers true
      op.visar_window_zcompensation(material="LiF", thickness=400e-6)

•  

  Take a reference

  Code Block
  language py theme RDark linenumbers true
  op.ref_only( xray_trans=0.2, xray_num=5, shutters=False, dark=0, daq_end=True, calibrant="", rate=1, visar=True, save=True, slow_cam=False )

•  

  Take a shot

  Code Block
  language py theme RDark linenumbers true
  op.optical_shot( shutter_close=[1, 2, 3, 4, 5, 6], lpl_ener=0.3, timing=5.0e-9 xray_trans=1, xray_threshold=0.2, save=True, daq_end=True, auto_trig=True, auto_charge=True, visar=True, debug=False, ps_opt=True )

•  Temporal overlap
  
  •  

    go to Ti sample

    Code Block
    language py theme RDark linenumbers true
    op.ti()

  •  remove the Be CRL
  •  open slit4 to 400 mic

    Code Block
    language py theme RDark linenumbers true
    op.ti()

  •  
  •  set full X-ray transmission
  •  open the pulse picker
