are installing a CM200 FEG in our facility. However, we are having
issues
with flash overs that are happening shortly (~24h) after reaching the
high tension of 200 kV. We have tried a few things to improve the
stability of the system: change the HT cable from the HT tank to the
microscope, cleaning the IGP2 pump or ramping up
the HT slowly to 200 kV with small voltage steps (< 0.2 kV).</span></font></span></font></div>
