keyword=Day shift summary
It was a pretty smooth shift.
There were 2 runs on Dummy with high current of 90uA while the limit was clearly posted to be 40uA. Hopefully, we didn't ruin the dummy target.
While we were moving the target, Q1 magnet tripped to zero. We had to reset it mannually by pressing the button in the middle room. It took about half an hour to recover from this trip.
After that we returned to 4He target, beam was not steady for about an hour, and there was no beam for another half an hour (it was taken off for tuning). Otherwise everything was smooth.
The summary of runs:
Run Target Events Current
2732-4 4He 1.25M 90uA
2735,6 Dummy 90uA High Current!!!
2738,9 Dummy 40uA
2740-6 4He 1.25M 90uA
