This might have been answered before but I looked at one png file and one tiq file from the same run that was stored on the server. There seems to be an

is at ~2.8 s???? Is the looper introducing this offset? |

After looking through >800 shots from Jul 2nd 21h to Jul 3rd 05h, we couldn't find a single example of a "smoking gun" isomer decay. I.e. I'm talking about
the examples Liliana posted earlier. We did find many examples (roughly 10%) where the ion track spontaneously
disappeared, but this shouldn't be the isomer as there was no frequency shift.

The gas bottle has been changed and the beam is back. |
Sun May 9 13:53:07 2021, Yuri, Wolfram, Andrew, Liliana, Calibration, Change of energy: Back as before
|
After looking at the spectrum it was concluded that the same isotopes, and no more, could be identified.
Now we change the energy back to 441.7 MeV/u and will open the scrappers to see if Mn comes in.

Fri May 7 09:36:32 2021, Ragan, Andrew, Yuri, General, Beam stop at 0928, adjust scope
|
It was requested from the SIS to stop the beam at 09:28
Yuri is adjusting the scope in order to avoid UFO (unidentified frequency object) |

|
From 4:05 to 4:15 beam intensity was 1/2 as before. |

|
Intensity went up from 5e8 to 1e9 extracted particles from SIS. |
Sat May 8 15:18:23 2021, Michael, Wolfram, Yuri, General, Beam Settings changing
|
Beam settings are being changed back to 78Kr beam at 467 Mev/u. |
Thu May 6 14:28:32 2021, Helmut Weick, Calibration, Be target thickness calibration -> 1839 mg/cm^2
|
Injection was optimized before with Cu-40 mg/cm^2 stripper.
This reduces energy of 78Kr from 370 MeV/u -> 386.52 MeV/u.
To keep the same ESR injetion the SIS energy was raised with Be 10mm tatget.

Sat May 8 01:43:23 2021, Helmut Weick, Accelerator, 70Se setting
|
If gamma_t = 1.3955 Tm stays, we will need Brho = 6.21902 Tm for 70Se.
The corresponding ESR Brho setting will be a bit shifted.
It then requires E-SIS = 446.55 MeV/u to get 70Se to this Brho and gamma_t.

Using the scripts I posted previously, I summed 5.5 hours of data from midnight to 5:30 July 2nd CEST.
I used 10ms time steps for better time resolution, but that did leave questionable frequency resolution. If anyone would like to see higher resolved frequency
