> The ESR status in the monitor stayed blue. No obvious sign that a magnet was down. The operators are checking

Fri Jul 2 01:31:35 2021, The remote Canadian beavers (Iris, Guy), Analysis, First spectra after bottle change 
|
The first good spectra after the gas bottle change is from 23:38:25 (on the 410 MHz Analyzer) |
Sun May 9 05:11:55 2021, 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.

Sun May 9 02:19:04 2021, 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. |
Wed Jun 30 20:58:06 2021, Ragan, Helena, General, Few minutes of disruption
|
There was a disruption from the SIS side for a few minutes. |

Sun May 9 02:45:50 2021, Jacobus, Michele, Shahab, Runs, Example of possible 52.Mn isomer
|
this is how it should look like |
Sun May 9 02:51:44 2021, 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.? |
Sun May 9 03:24:12 2021, 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).

Fri May 7 17:12:14 2021, Kanika, Sergey, Yuri, Wolfram, Michael, Shahab, Runs, Energy change -6 MeV/u
|
changed the energy down to 435 MeV/u |
Fri May 7 17:35:22 2021, Kanika, Sergey, Yuri, Wolfram, Michael, Shahab, Runs, Energy change +6 MeV/u
|
We will now go up in energy to 447 MeV (+6 MeV) from the original energy
last file name with previous energy:

Thu May 6 21:26:02 2021, Yuri et al., Accelerator, Energies
|
gamma_t = 1.3955
Br(72Ge) corresponds to 6.79575 Tm
E (Kr) at Br(72Ge) = 392.9 MeV/u
|
Mon May 10 08:49:01 2021, Kanika, Alex, RuiJiu, General, End of the measurement
|
The beam was stopped at about 08:40. |
Fri Jul 2 13:44:50 2021, Sergey, et al, Accelerator, El cooler
|
Up to now, attempts to cool the fat line between Se and Ar were conducted. We give up it now and remove cooling |
Sat May 8 10:51:41 2021, Akash, Nic, Jelena, Zsolt, Calibration, ESR settings seem different
|
Settings don't look the same...so we are not yet writing files unless sure. |
Thu May 6 17:48:48 2021, W. Korten, Helmut, General, ESR setting for 72Ge ions with primary beam
|
Setting the 78Kr (after the target) to the Brho of the 72Ge beam at 368.4 MeV/u (gamma=1.3955), i.e. 6.79575 Tm, which leads to an energy of 392.93 (of
78Kr).
With the 10mm Be target the beam energy should then be 467.8 MeV/u .

Fri May 7 10:05:06 2021, Yuri, Accelerator, E02DS3HG does not drive
|
E02DS3HG stays at -35 mm and does not react |
Wed Jun 30 20:14:44 2021, Ragan, Helena, General, Drop in SIS intensity
|
There is a drop in SIS intensity and the operators are informed. |
