      Continue by checking the alignment of the drive lasers

      •  

        Set the system in a mode where the laser energy is minimum, the filter is removed from questar 1 and the trigger is enabled

        Code Block
        languagepy
        themeRDark
        linenumberstrue
        op.check_front_alignment()
      •  Confirm you see a scattering signal close to the X-ray cross (342, 561)
      •  

        Move the hexapod X axis to center the beams on the cross and produce a round scattering signal (steps of 50 mic is good)

        Code Block
        languagepy
        themeRDark
        linenumberstrue
        x.hex_x.tweak(0.05)
    •  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). Steps of 50 mic is good.

        Code Block
        languagepy
        themeRDark
        linenumberstrue
        x.visar_z.tweak(0.05)
      •  

        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
        languagepy
        themeRDark
        linenumberstrue
        op.visar_window_compensation(material="LiF", thickness=400e-6)
