CURRENT TECHNOLOGY Electron Gun / Power Supply Systems with FlexPanel Controller. This section contains information for standard systems built in 2005 or later.
Also see the manual shipped with the gun, especially the Data Section (performance graphs taken with the gun during testing)
Call Kimball Physics. Any troubleshooting questions will be answered by experienced employees who actually build and test the guns or power supplies. Because of possible High Voltage dangers, it is advisable to call the Electronics Dept for guidance in troubleshooting the power supplies.
Electron guns and power supplies can be returned to Kimball Physics for evaluation / rebuild. Call for a return authorization number. Rebuild of an electron gun will include evaluation, cleaning, installation of a new cathode, and testing. Repair of a power supply will include evaluation and testing. It is best to return the complete system ( gun, power supply, and cables), so they can be tested together.

Electron Gun / Power Supply Systems (Pre 2005)
This section contains information for systems built before 2005 with power supplies using analog control. These older supplies usually have both digital and analog meters, as well as a number of separate potentiometers on the front They do not include the FlexPanel controller.
NOTE: Before attempting to refurbish an older system which has not been used for a number of years, please consult Kimball Physics.
Due to possible High Voltage hazards, it is advisable to return the entire system to Kimball Physics for evaluation/rebuild. Replacement manuals may be available for older systems at a cost. When calling or writing, it is helpful to have the serial numbers of the electron gun (usually engraved on a gun flange) and the power supply (usually on a tag on the back of the unit).
