d. Check the burn at the second wedge optic using the test aperture.
The beam must be unclipped. If not, repeat steps "a" and "b" above until both pass with the
adjustments mechanisms locked down.
e. Make a burn into the test aperture with all four channels turned on.
The resulting burn footprint should be circular in shape and contained in the aperture (no
clipping).
f. Remove the service attenuator (SW4 on the CPU PCB to the right).
g. Perform the System Checkout as outlined in Topic 3.4
3.2.5 Pyro Detector Alignment
In order for the calibration of the system to be as accurate as possible, the pyro detector mirrors must be
properly aligned. This alignment may also be required if the Optics Bench PCB is changed.
1. Set up of the laser.
a. Go into the service screen and enter the following parameters. Turn on one Holmium
flashlamp and set the lamp energy at 50 Joules, lamp volts at 800V and repetition rate of 10
Hz.
b. Set the oscilloscope for 1V/Div. with sweep time of 200µS.
2. Align the pyro mirror.
a. Connect channel A from the oscilloscope to TP1 (MPREA) on the Optics Bench PCB. Use TP2 as
ground.
b. Adjust the pyro mirror in both X-Y axis to peak the signal as seen on the scope.
