15:30 We have a break due to an issue at UNILAC (quadrupole failed). Also radiation safety interlock was triggered at the fragment separator. This also pushed a faradaycup into the ESR (GE01DC3VP).
Just before the issue during the last bunching, the peak was misaligned to the marker in the Schottky. The marker was sitting on the right flank. So the electron-cooled 229Th did not match with the bunching frequency anymore. We are preparing to adjust the cooler voltage to fix this. For some reason the frequency recovered and is back to its original position. However, our accumulations do not seem to work as well as before, we stagnate much earlier and at a much lower level.

15:50 Beam is back, Carsten is still investigating the drop in intensity we saw before the UNILAC failure.

17:15 TE slits were on -8 and +8, opening to -11 and +11, no change to acquisition pattern, something is still wrong

18:00 We were locked out by HHT people for 30+ mins

18:27 We had to call in ESR support
