JEL, ZN | General | Screenshots 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. |

Night shift starts with no injections from SIS! We still have triggers; we called HKR and are waiting for response. |

Shahab | Detectors | 10GB cables for the DAQ rack |
We have been working together with IT on the speed of data transfer: with the new 10 GB interface we can now transfer data from NAS to Lustre with 400MB/s. From NAS to GPU Computer up to 700MB/s. All cables around the rack are now 10GB capable. |

ID | General | FYI 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. |

ID | General | Spill 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... |

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, Maeve | Accelerator | Still not a good beam in the ESR |
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. |
