    Continue by checking the alignment of the drive lasers

    •  

      Decrease the energy of the laser to its minimumSet the system in a mode where the laser energy is minimum, the filter is removed from questar 1 and the trigger is enabled

      op.HWPon("all", set_T=0)

    •  Confirm the filter of Questar 1 is in position 2 (no filter) to allow all wavelength to be seen
    •  Adjust the signal on the camera my moving the slider 'max' to the maximum value and set the gain to 0
    •  Set the NsSlicer to 10Hz and then click on the corresponding button which says 'ENB'

    • check_front_alignment()

    •  Confirm  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
