GSO High Voltage study
- is the problem with the GSO high voltage beam related? Look at
current drawn as a function of high voltage, with beam off. I
don't know what the nominal current at 100 µA or with no beam has
been in the recent past, but from the Striptool it seems that the current
was about 1450 µA, (at 1800 V) independent of the beam being on or
off. Now, the beam off value is about the same, but the
current goes way up when the beam comes on. Problem with beam
High Voltage Current
1400 815 (beam on at 100 µA)
1500 1246 (beam on at 100 µA)
1500 977 (beam turned off deliberately)
1600 1140 "
1700 1306 "
1800 1471 "
- turn beam on again at 100 µA High Voltage trips again!
