Michael, Ruijiu, Helmut, Yuri, Wolfram, Sergey, Shahab | Runs | started data taking with high resolution |
after optimizing the scrapers we have reached the highest possible resolution in the isochronous mode.
starting data taking with this new settings.
last files before this settings were:

Jacobus, Shahab | Runs | First 52Mn run |
Run E143-245 MHz-2021.05.09.01.17.42.265.tiq is the first run of the experiment on 52Mn. |

Jacobus, Shahab | Runs | possible 52-Mn isomer |
the intensity of the line on the left side is so high, it is difficult to see the isomers in the middle as can be seen in the auto generated picture |

Iris | Runs | Example of possible 52.Mn isomer |
So the "isomers" pop up at ~-600 Hz and +580 Hz... is the -600 Hz on the left the 378 keV isomer (21 min) and the +580 Hz on the right the g.s.? |

Iris (Shahab, Jacobus, Chris G., Michele) | Runs | Example of possible 52.Mn isomer |
Short update from Yuri: these are not our isomers. These are 45Sc (left, 12 keV isomer not resolvable) and 75Br (center), and the right-most peak of the triplet is a satellite (has a different line shape, much narrower).

ESR warning (colour red in the panel)
Operator intervention required.
Runs affected by this issue:
-from E143-245MHz-2021.05.09.02.49.48.521 (03:50)
-to E143-245MHz-2021.05.09.02.54.54.239 (03:54) .

Iris (Chris G., Jacobus, Michele) | Runs | First 52Mn run (no 52Mn unfortunately) |
> Run E143-245 MHz-2021.05.09.01.17.42.265.tiq is the first run of the experiment on 52Mn.
And Run E143-410MHz-2021.05.09.03.27.37.368.tiq from 2021-05-09 03:27 is the first run on the 410 MHz detector. Started a bit later than the 245 MHz detector.

Iris, Chris G., Jacobus, Michele | Runs | Triplet: zoom in |
Zoom into the triplet: the satellite peaks on the right are clearly visible.
This is just one file but one *might* see some substructure. Yuri mentioned a 318 ms isomer in 45Sc at 12 keV but that cannot be resolved.
Maybe someone can look at the added-up ROOT files if that looks better or is just statistics?

Liliana Andrew | Runs | Stopped data taking during modifications for the beam energy |
Beam energy to be increase to move Mn into the ring.
First step we set the energy to 445 MeV.
The effect of the change can be seen on the plot: Right is how it was before and left after the change. |

Shahab | Runs | 72-Ge setting |
the new setting is roughly 400 khz lower in frequency.
Previous beam time Ge was on 243.100 now it is on 242.74
we decided to use the higher harmonic:
expecting it on 244.66 MHz |
