19	Thu Mar 17 17:56:33 2022	Kristian	Calibration	HV dividers	PTB HV dividers arrived. Divider ratios are: PT120: 12003,341
46	Thu Mar 31 22:41:35 2022	Kristian	Calibration	HV divider	We noticed a difference in the electron cooler high voltage:
56	Fri Apr 1 18:19:58 2022	Kristian	Calibration	HV divider	We checked the strange behavior of the HV dividers again. The Ohmlabs and the PTB divider are in good agreement at 120 kV and 150 kV.
17	Wed Mar 16 12:04:40 2022	Kristian	Detectors	HV cable to particle detector South	Checked HV cable to particle detector south. Label is HV2 Scraper.
100	Tue Apr 5 15:25:47 2022	Sebastian, Kristian, Pierre-Michel	DAQ	Go4 Conditions for "TDC_stacked_Sig/Ref" histogram	First version of TDC_stacked histograms implemented. Under folder "Conditions" you can now integrate
88	Mon Apr 4 15:32:38 2022	Kristiand & Sebastian	DAQ	Go4 Backup Code	Due to some code changes (PMT over wavelength historgram) Kristian and I backuped a working Go4 code in the current go4 folder on the

65	Sat Apr 2 15:54:32 2022	Carsten	Accelerator	ESR setup with primary beam and 1cm Be plate + Schottky data on NTCAP	MArkus and Bernd have setup the ESR with the thick stripper foil and put the ion beam (238U92+) on the central orbit.
112	Wed Apr 6 16:01:07 2022	BL	Accelerator	ESR settings before adjusting laser: 2022-04-06_14-37-30_ESR_EXP22_02_238U92_Brandau_30March22.C1.txt	# Version: 1.2 # Comment: ParamModi Export at 2022-04-06T14:37:35.957978+02:00[Europe/Berlin] # Context: ESR_EXP22_02_238U92_Brandau_30March22.C1
107	Wed Apr 6 09:30:53 2022	Danyal	Accelerator	ESR is blue again - errors are fixed	The ESR is "blue" again. The errors (scu related) have been fixed.
106	Wed Apr 6 08:31:54 2022	Danyal & Regina	General	ESR had some errors	Regina noticed that the ESR was "red" This means that there are some errors.
50	Fri Apr 1 02:29:40 2022	Carsten		ESR Cooler crashed	ESR cooler crashed. We could not restart the cooler. Since we had several other problems, we stop now.
117	Wed Apr 6 22:29:55 2022	Patrick	Accelerator	ECooler voltages	ECooler voltages: [B]06.04:[/B]
9	Fri Nov 5 17:23:23 2021	Rodolfo	DAQ	Dye trigger out	The dye laser offers different scan settings (see pages 65 - 67 of the user manual). We are using the following setting, see attached
14	Thu Mar 3 21:39:21 2022	Rodolfo	Laser	Dye solution, DCM in Ethanol and DMSO	I have prepared a new dye solution of DCM in Ethanol and DMSO (1:1). The concentration of the "oscillator + preamplifier" is 0,3
235	Fri Apr 15 20:43:18 2022	Konstantin	Laser	Dye changed	Dye of the laser system has been changed. UV laser power increased from ~8 mJ to 11 mJ pulse energy.
