ASSEMBLING MODULES

 

BeamPeriscopeAssby_2AxisStages_Solid

1) Glue a right angle mirror MRA20-P01 to polaris mount using norland 81, making side flush to bottom of mount and front flush to top of mount.
2) Glue a right angle mirror MRA20-P01 5.1 mm from edge with dial, and flush with the back of the stage.
3) Attach stages to the SolidPeriscopeBase, and attach the polaris mount to one of the stages in the correct orientation.
4) Remove redundant knob on polaris mount, as it should not be adjusted

Resonant mirror assembly: ResMirrChamber

1) Screw in schneeberger slider from underneath, make sure to use the correct 10 mm long screws so as not to damage stage
2) Add the stop screw, spring plunger, and threaded bushing (remove the lock screw) and lock nut, knob, and screw for positioning the stage.
3) Glue in the CRS resonant mirror cable using a black RTV sealant (Dow-Corning 732 multipurpose sealant), leaving 7" outside of the chamber. Let the glue cure overnight.

4) resonant mirror alignment in alignment rig - see photos below
UV cure a mirror to the resonant mirror alignment jig. 
Slide the body of the resonant scanner inside its mount and then attach the mount to the alignment jig. 
The alignment jig now has a mirror mounted on it – this is a reference point for the orientation of the resonant mirror. 
An alignment laser should hit the resonant mirror and the alignment mirror at the same time.
Adjust the orientation of the resonant mirror carefully so that the two reflections overlap.  
Height of the top edge of the resonant mirror should be 2.7 mm.

From left to right: Alignment jig with resonant mirror and alignment mirror; close-up of laser beam hitting the resonant mirror and alignment mirror; reflection from the two mirrors before alignment; reflections after alignment – they are on top of each other; height – resonant mirror center should be aligned with top edge of alignment jig (2.7 mm between edges).
5) At this point the resonant mirror can be mounted in the chamber. This is fairly tricky as it requires management of a fairly short cable. 
Attach the cable to the mirror
Grab the resonant scanner mount with vice grip and inser into the chamber
The cable has to be trapped under the bottom of the mount - screw to the bottom of the chamber while pushing towards the alignment edge

PMT assembly
The goal is to couple the lens onto the PMT face with oil
Seal the edge of the PMT face to the PMT housing with 5 min epoxy - careful not to soil the plate above the photocathode 
Add 30 - 50 ul of high viscosity oil
Place condensor lens on oil. Make sure there are no bubbles and carefully remove overflow oil from the housing.
Place a thin ring of quick seal (WPI) on the PMT housing around the lens
