Thu Apr 3 23:23:20 2025, Zhang Min, Zhou Xu, Accelerator, Beam injection change
|
The SIS operator says that FRS doesn't need beam now, ESR will receive the full SIS beam extraction every 3 secs overnight. All the secondary beams are
injected into ESR from now on. |

Tue Apr 1 02:01:06 2025, Zac, Shahab, Ruijiu, Yuri, Sergey, Wolfram, Carlo, Michael, Accelerator, Settings lost
|
| Settings lost after the beam was lost. Trying to recover particle identification now that beam has returned. |
|
Wed Apr 2 23:15:52 2025, Zac, Johan, Accelerator, No injections from SIS
|
| Night shift starts with no injections from SIS! We still have triggers; we called HKR and are waiting for response. |

Thu Apr 3 01:19:44 2025, Zac, Johan, General, Beam fluctuations
|
| Beam gone again between 01:14 and 01:18, then again at 01:19. HKR says there are problems with the source. |

Thu Apr 3 01:56:57 2025, Zac, Johan, General, Problems with one of the quadrupoles
|
| 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. |
|
Thu Apr 3 02:01:29 2025, Zac, Johan, General, Quadrupole issues
|
| HKR has called someone to fix the quadrupole, they think it will take about an hour. |

Thu Apr 3 06:33:08 2025, Zac, Johan, General, Beam lost at 06:27, returned at 06:34
|
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. |

Wed Apr 2 04:59:50 2025, Zac, Chris, Carlo, General, Receiving injections but not seeing anything on RSAs
|
Starting at around 04:09 we don't see anything on RSAs. RSAs are still triggering and writing files, but only see noise. Lassie indicates beam current in
the ESR
|
|
Wed Apr 2 00:59:43 2025, Zac, Carlo, Chris, Accelerator, Lost the beam
|
| Beam was lost from 00:44 until 00:59 |
|
Fri Apr 4 17:59:33 2025, Zac , Sid, DAQ, 17:58
|
DAQ stopped with last file in RSA1-2025.04.04.17.58.49.340.tiq
Now the plan is to change one of the analyzers to narrow band recording for longer from the 245 Schotkky. |

Tue Apr 1 15:32:59 2025, Zac, DAQ, NTCAP Restarted
|
| NTCAP Has been restarted (we restart every day around 15:00 so data goes in a new folder) |
