  89   Wed Apr 2 18:22:30 2025 IDGeneralSpill cycle distribution
The spill cycle distributions is absolutely nuts since beginning of the shift. On the positive side: we got a lot of spills since FRS did not take many, so I think we got more than our parasitic 1:10 share...
  90   Wed Apr 2 18:31:52 2025 IDGeneralFYI for morning shifts Thu
The PLEIADES team (pocket detectors) has discussed with Wolfram to get access to the ESR tomorrow (Thu) morning ~8:00 to check their detectors and install a dry N2 flow connection. This might take about 1h. Iris (or Jan) will call the HKR to get the RP shift for the transport of the N2 bottle into the ESR. Morning shift will be informed accordingly when we are onsite, just keep running (keep running...keep running...keep running) until we get access.

  99   Wed Apr 2 23:40:23 2025 JEL, ZNGeneralScreenshots taken just as beam came back
We are seeing spills being received but no peaks are seen in the analyzers. 

We are seeing several intermittent losses of beam. Awaiting action to see if it stabilizes.


23.51 Beam is back and we see the nice spectrum in the analyzer.

Beam gone again between 01:14 and 01:18, then again at 01:19. HKR says there are problems with the source.

Since around 01:45 we get spills but see nothing on analysers. HKR says there is a problem with one of the quadrupoles; they are working on it.
  105   Thu Apr 3 02:01:29 2025 Zac, JohanGeneralQuadrupole issues
HKR has called someone to fix the quadrupole, they think it will take about an hour.

Spike in beam intensity at 06:27 (5x usual intensity) and then beam is lost. HKR says it's a problem with the magnet's power supply. Once the beam returned, the peaks are shifted to the left but are slowly shifting back into position.
