keyword=trippy beam, reduced current to 57 µAbeam has been very trippy over the last 2 hrs. i vaguely recall that sometime in the past when we've seen this before, it was because something something was charging up and then discharging. the solution then was to slightly lower the beam current until it stopped happening. i don't know if this is the case now, but i thought it wouldn't hurt to try it. to that end i requested that the beam current be reduced from 58 to 57 µA. we'll see if this helps...
