It was noted yesterday during the TM2 Source HV tests that the E-rig was not running accordingly through the beam.
Upon turning on the PS, there a 45 second or so delay before the needle drops to the right at +500V and the PS no longer responds. (similar issue |

The performance of the roughing pump has gradually gone down. Notably after the system has been vented. See attached screenshot from the archiver.

Testing the HV bias I found that the einzel lens was behaving strangely. When I tried to put it higher than 1kV, the current would start spiking
from 12uA to > 100uA. The voltage would jump around quite a bit as well (+/- 100V). Everything seems the way it was before, except the EZL power supply |
