|
time = 20:00
The RF has been adjusted so that it bunches at the correct frequency for 209Bi

Mon May 9 17:14:02 2022, Carsten, DAQ, NTCAP DAQ
|
The NTCap DAQ computer in the HKR (Schottky logbook) is started, and all preparations for data taking (mounting of NAS etc.) are done.
Parameters for NTCAP DAQ will be adjusted as soon as beam is available. |

Mon May 9 17:16:34 2022, Carsten, Accelerator, Important: New ESR pattern - requies action for XUV detector in/out
|
The ESR pattern is enhanced compared to the thorium experiment by additional machines that can be used for cooling/waiting in order to optimize 208Bi yield.
As a consequence, the sub chain numbers (previous: virtuelle Beschleuniger) are changed. The new numbers still have to be dialed in into the devices in
the Messhütte and the automatic in/out of the XUV-detector tested- |

Mon May 16 17:15:56 2022, Carsten, Analysis, DAQ /Analysis - shift of peaks in the accumulated spectra, changes in code
|
After a phone call with Wilfried I implemented an offset to all hit channels of the stacked / accumulated spectra where one chekcs the timing peaks.
Therfore, I made a copy of the analysis in 208Bi1 (one "1" at the end). And here, in the file TLdaAnlProc.cxx I added an offset of +70 to the hit channel |

Mon May 30 20:58:26 2022, Carsten, Accelerator, New Settings for 208Bi Beam
|
Old SetParameters.C and old SetConditions.C were saved as SetParameters_209.C and SetConditions_209.C
The ion beam settings were changed to 208Bi82+:

Thu Jun 30 11:12:21 2022, Carsten, Analysis, Updated Go4 Analysis with small Bugfix (PMTOverWavelength SPectra)
|
Here attached is a more recentversion of the Go4 Analysis Code with some smaller bugfixes.
For adaequate *.C files please have alook in 208Bi go4 directory on the atplaser account.
Please note, that there is also a (not fully up-to-date) description/manual somewhere here in the Elog. |
