| If moving IRBC23 using the pico7 gui does not change the alignment, then the flex mount is not touching the actuator. Push on the mount and then turn the knob by hand. Confirm that the picomotor can control the motion again. | If moving IRBC23 using the pico7 gui does not change the alignment, then the flex mount is not touching the actuator.

| - | If you have trouble figuring out whether the laser is going through the hole in the middle of the cold stop, you can place the cover on NIRO. Looking at Beam 3, compare the location of the spot coming from the fold mirrors IR123A, IR123B, and IR23. Move the misaligned optic until it overlaps with the other beams. This could bring the light close enough so that it appears on the pixel area of the detector. Then the remainder of the alignment can be done by aligning to the spots on the dectector using the 5 Steps listed above. | + | If you have trouble figuring out whether the laser is going through the hole in the middle of the cold stop, you can place the cover on NIRO.
