keyword=beam current excursion
After performing the Q2 measurement and while we were dealing with target issues, we saw the beam current jump from 0.25uA to 11uA for 30seconds. The VDCs had already been turned off, but the other devices were still at their counting-mode values. Run 2874 was taken afterwards, and S0/S2/Happex detectors look fine (the same as before).
MCC called to inform us afterwards and apologize: they had some script-problems after trying a QE measurement, and shut the beam off as soon as they noticed.
