Sergey Litvinov, Xinliang Yan | General | Tuning of the ion optics |
From roughly 10:45 pm to 11:05 pm, Sergey tuned the
ion optics of the ESR to see if the mass resolution at
413.55735 MHz improves or not. Please note that the
frequencies of ions during the tuning process are not
stable.
Q-magnets and S-magnets have been adjusted, see
accelerator E-logs ID-844 titled ‘ ESR seting for
204Pt77+’ created by Sergey. |

Ruijiu, Wolfram, Xinliang, Wangqian | Analysis | The spectrum of 194Pb82+ vs 184Pt78+ |
In summary, the statistical results collected between 5:00 and 12:00 AM on April 2, 2025. For each injection, we calculate the frequency mean value
(f_mean) and the peak height (P) of 194Pb ions for frames with t > 0.14 s, correct each injection’s frequency by subtracting f_mean, and only sum
the
spectra from injections with P > 100; moreover, by comparing the 194Pb82+ spectrum with that of 184Pt78+—whose isomer at 1.8 MeV (T1/2 = 1 ms) is
clearly visible—the setup is demonstrated to be suitable for detecting an isomer with a lifetime of about 1 ms.
===================================================================
How to dod analysis and plot this result:
1. Add up injections and create accumulated spectrum.
(pyroot) gpuuser@appc256:/data.local/G22-00018_00203/scripts/OnlineDataAnalysisSystem/shift/20250331/data$ sh generate_data.sh /data.local/G22-
00018_00203/results/analyzers/RSA01 RSA01-
'*.tiq_spectrogram.npz' 2025.04.02.05.00.00.000 2025.04.02.12.00.00.000 0.001 408.59e6 408.62e6 0.1 1
After run this command, you will create the accumulated spectrum under the folder with time stamp of start time and stop time.
2. Download the code "plot_fft.cxx" and plot the spectrum with following command:

Michael, Alex | Accelerator | The beam is back in the ESR |

The Schottky spectra look the same as before.
The ESR experts could not exactly identify the problem which caused this loss of the beam. |

Michael, Alex | General | The beam is back |
The beam is back. But, the experts have found a problem with one of the modules of the SIS kicker magnet. And, currently they have disabled this module. This fixed the problem. However, since the kicker system is not running with full power, it is not clear by how much this can affect the extracted beam intensity for the ESR. Therefore, the ESR experts have been called and they will look at the injected beam intensity in the ring, in order to know if its still the same as before disabling the module.
The experts will discuss at the upcoming meeting how to proceed with the damaged module, i.e. when to repair it.
In addition, the FRS started to take the beam now (again) which means that we will be getting less pulses from SIS as compared to the previous night. |

The repair of SIS electron cooler power supplies
In the meantime we received a few injections and confirmed that 194Pb setting is still as it was before entering into the ESR
Now we change to 208Pb82+ to do several ESR accelerator tests
Esis = 517 MeV/u
Change the beamline to 208 Pb 82+ and the ESR to 208 b 82+ and NO other changes |

The (power supply of) SIS kicker magnet has been repaired and the beam has been restored from about 14:20.
But, the Schottky spectrum in the ESR looked pretty bad, so the measurement can not be restarted.
The accelerator experts are currently looking into this problem. |

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... |

Michael, Alex | Accelerator | Some empty injections triggered while beam patterns are changed |
Operators seem to play with spill cycles, we get every 1:1 shot, then 1:10 again. During this, we noticed a few "empty injections" beeing triggered in the RSAs. They light up green, but spectrum is flat. Then it returns to normal operation again. |
