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.
The picture shows the effect of going back to the previous energy and then the effect of opening the scrappers |

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) |

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.
For exactly 1850 mg/cm^2 a SIS-energy of 445.46 MeV/u would be needed. A scan of SIS energy resulted in 445.0 MeV/u as optimal.
This means target thickness is close to 1850 mg/cm^2, we can call it 1839 mg/cm^2. |

Fri May 7 12:37:35 2021, Ragan, Andrew, Yuri, Alex, General, Back with beam

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

Sun May 9 12:53:01 2021, Desislava Kalaydjieva, Taka Yamaguchi, Analysis, Analysis, Morning shift, 9 May 9x
|
For the whole morning shift there were no significant changes in the spectra.
Some of the obtained histograms are attached below.
The python code was used and the histogram was plotted in ROOT with log y scale.
The time, the used code options and the data type are marked in the filenames or in the description below.
Attachment 1-4: 245MHz, options used " -s 5.1 -t 0.5 ", time marked in the filename (time as in the title of the files on the server (-1h of the real time)).
Attachment 5: 410MHz, with the same options for the python code, real time names. It is different from 245MHz histogram.
Attachment 6: Comparison between 245MHz histogram and 410MHz histogram for real time 10:00 - 11:00.
Note: This difference is observed in the histograms from the early morning hours too (checked up to 4 o'clock).
Attachment 7: 245MHz data, with options "-s 5.0 (Red) / -s 5.05 (Green) / -5.1 (Blue) -t 0.5" (real time 08:00 - 09:00)
Attachment 8: 245MHz data, with options "-s 5.0 (Red) / -s 5.05 (Green) / -5.1 (Blue) -t 0.1" (real time 08:00 - 09:00)
Attachment 9: 410MHz data, with options "-s 5.0 (Red) / -s 5.05 (Green) / -5.1 (Blue) -t 0.5" (real time 08:00 - 09:00) |
