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.

Fri May 7 09:56:43 2021, Yuri, Calibration, Identification Verification
|
With closed scrapers there are only a few weak lines.
Open temporarily all scrapers in the ESR to write down the frequencies. |

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. |

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 01:07:27 2021, Helmut Weick, Analysis, maybe frequency ID
|
We think we see the frequency range of A/q=2.25 at 243.1 MHz.
This would correspond to L=108.2m and E=386.4 MeV/u (gamma_t = 1.3955) at h = 126.
Path length is a bit short, for L=108.4m it should be 370.6 MeV/u.

Sun May 9 05:38:29 2021, Iris, Chris G., Analysis, offset btw png and tiq files from server?
|
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
offset of 2.2 s. The png file from the server (right) shows the injection at ~5s, whereas when I look at the tiq file in the GUI (left), the injection
is at ~2.8 s???? Is the looper introducing this offset? |
 Sun May 9 05:54:11 2021, Ragan, Analysis, offset btw png and tiq files from server?
|
| This is due to the 50% trigger setting in the spectrum analyzers )) |

Attached is a summed spectra of all files taken between 1:17am and 1:59am (on the 245 MHz detector).

Sun May 9 17:39:21 2021, Guy, Analysis, Comparison between 72Ge: 7th 19h vs 8th 21h

Following Xiangcheng Chen's analysis, I analysed 11 ms time slices separated by 25 ms to see the evolution of the potential isomer across the injection.
