plunger motors were set
to +/-390 mm for 245 MHz resonator

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. |

Sergey | Accelerator | Tune to 98Zr |
- stop longer measurements
- change quadrupole and sextupole magnets
- rescale SIS-TE-ESR |

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 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 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. |

Boguslaw, Camille | Runs | Injection pattern changed |
The injection pattern changed on Lassie monitor (0:27 AM). (picture 1)
It when back to the previous rate at 1:48 AM. (picture 2)
The same pattern change appeared from 3:01 AM to 3:07 AM. (picture 3) and from 3:24 AM to 3:39 AM. |

Helmut Weick | Accelerator | Cooler curves after beam shift |
After the Beam position tuning but before the scraper tuning two more cooler curves were taken.
The first with all scrapers open shows a similar shape to before with the same quadrupole setting.
Afterwards the ESR ebergy was shifted by -0.8 MeV/u to get the beam more on an outer orbit.
The curve then is shifted and has a bit less acceptance. |
