Hello,
When I turn on my electron beam, no image appears on the TV screen. I have also noticed that the adjusting the condenser and objective lens settings in Augermap do not affect the emission current. I checked all the connections and there are no shorts or
discontinuities in the analyzer, lens coil, lens deflector, and octupole deflector. This problem started when I began sputtering using 1kV ion beam. Can you advise on what the issue might be or how to resolve it?
