=== Repair and Enhancement Notes=== * Before repair, disable pumps and high voltage then put it into operation mode by placing a magnet on the operation relay. * schematics framed behind SEM are to a similar, potentially slightly more modern model * poorly designed wire harness may cause linear op amp and transistor on the J1 board of the power module to fail. * camera mounting stage and bellows hood for slow-scan exposure. Proposed (2010-06-15), Completed by Mike, Miloh, and Chris (2010-11-06) * CRT V. scan, V bias, H. frequency potentiometers are located on the underside of the CRT module. * broken stigmator Y lock tab is in altoids tin in SEM kit box. How to mitigate vibration: # Measure and pinpoint vibration sources # Dampen vibration from the rough pump-line by one of these methods: routing it through a concrete block and adding a hose extension, sandbag the existing line, or utilize water as a mass. # Hang the column from the ceiling with bungee cord and platform # Potentially relocate the microscope to the server room to diminish dust and increase distance from Mission St. # Create spring clamping specimen slug to keep the specimen from moving.
