| Recording Zr starting from 14:45 again back to short cycle. |

Fri May 17 23:30:16 2024, Shahab, General, HHT people inside
|
| no beam since about one hour, also HHT people inside since about 10 min. |
|
Sat May 18 00:06:56 2024, Shahab, Runs, HHT people out again
|
| we try to re run the ESR. ESR behaves very strangely. Something not so right. |

|
Injection Beam Process: 100ms
Bunching Beam Process: 16ms
Intermediate Beam Process: 100 ms, which is repeated 140 times

Thu May 16 12:48:58 2024, Sergey, Accelerator, Tune to 98Zr
|
- stop longer measurements
- change quadrupole and sextupole magnets
- rescale SIS-TE-ESR |

Thu May 9 10:01:59 2024, Ruijiu Chen, DAQ, NI crate of NTCAP system can not be started.
|
After moving the NTCAP system from HKR to ESR Messhutte, we tested the system with a signal generator on 16th February and confirmed that it was functioning
correctly.
|
|
Thu May 9 15:59:30 2024, Ruijiu Chen, DAQ, Carsten checked the NTCAP system.
|
Exactly this was the question. If several devices fail at the same time and you look for the course you might get suspicious.
Anyhow,

|
If the ssh to lxir131 was disconnected, you can connect to lxir131 and restart queqiao program to transfer tiq data from NAS to luster.
1. Open a terminal on any GSI linux computer, like the one in the Measurement Room:

|
Data collection runs smooth so far.
Yuri Litvinov will start modifying SP magnets now. The resolution will change. |

Thu May 16 07:50:39 2024, Mayr, Hannes, Runs, Peaks with very high particle rate
|
| Peaks in the particle diagram going to unusual high 1.4e9 particles. |
|
Thu May 16 08:58:39 2024, Mayr, Hannes, Runs, Fluctuations in particle rate
|
| Particle rates are fluctuating and increasing from a constant 5e8 to something around 1e9. |
|
Thu May 16 09:41:56 2024, Mayr, Hannes, Runs, No beam
|
| No beam from 09:39 to 10:10 due to a setting change. The change aims to increase the measurement time to 10s. |
|
Thu May 16 10:18:14 2024, Mayr, Hannes, Runs, Beam back, DAQ off
|
Beam is back since 10:10, but DAQ is turned off to change the setting there.
Measurements starting at 10:18 are only test runs and should not be used for analysis. |
|
Thu May 16 11:08:27 2024, Mayr, Hannes, Runs, DAQ running again
|
"Real" measurement with good data starting from 11:07 until approximately 13:00.
Measurement time was changed to 10s with injections every 32s. |
|
Thu May 16 11:13:05 2024, Mayr, Hannes, Runs, Rates
|
| With the new timing, the rates now look like can be seen in the screenshot. |
|
Thu May 16 13:04:02 2024, Mayr, Hannes, Runs, DAQ stopped, change setting to 98Zr
|
| Beam tuning for 98Zr starting at 12:53, following data should be excluded from analysis. DAQ was stopped around 13:13. |
|
Sun May 19 12:04:55 2024, Kanika, Accelerator, Beam back
|
| The beam is back. |
