Thu Jul 1 23:38:55 2021, IK, KK, Runs, Change of gas bottle
|
| 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.

Thu May 6 22:05:30 2021, Helmut, Accelerator, Beamline and ESR data sets for 72Ge setting
|
| parammodi exports, E-SIS = 441.0 MeV/u with Be-1840 mg/cm² target in, isoc. ESR, at least we see fragments |
|
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) |
|
Sat Jul 3 08:12:22 2021, Dima, Yuri, General, Beam stop
|
We stopped the beam at 08:10

Thu Jul 1 04:15:54 2021, David, Liliana, General, Beam intensity
|
| 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.

|
We are back with the beam in the ESR since 12:30
