47	Fri Apr 1 00:27:27 2022	Carsten		Settings Particle Detectors /Tests with primary beam	All the beam settings will be given in a separate post.
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.
55	Fri Apr 1 16:46:33 2022	Carsten	Detectors	All pressuzied air drives are tested now and are working properly	All pressuzied air drives are tested now and are working properly
57	Fri Apr 1 18:30:38 2022	Carsten	Detectors	Positions / Voltages threshlds for particle detectors	[B]DC beam 238U92+ (205kV, e-beam)[/B] We used the detector NA_SZ to determine the central primary-beam (238U92+) position by
60	Fri Apr 1 23:47:45 2022	Carsten	Detectors	PMT thresholds / PMT north does not allow voltage abow ~ -1kV	Checked thresholds of PMT with beam and without beam.
Draft	Sat Apr 2 01:02:39 2022	Carsten		Test measurements with two DAQs	We do two measurements: One measurement using 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.
71	Sat Apr 2 22:43:36 2022	Carsten		Ring set-up for 229/89+, scraped and bunched, Iel=500mA at injection and 100mA during measurment	The ring SIS/ESR were set up for 229/89+. Pölease note that this not only 1e- Th but ponteially also the isobars of Ac (0e-1)/Pa(2e-,
72	Sat Apr 2 23:16:55 2022	Carsten		Cu mirror and CsI moved in and out of the ring	Ken tested the Cu-mirror and CsI disk Detector. They move without a problem and don't scrape the ion beam.
80	Sun Apr 3 13:05:08 2022	Carsten	Laser	Distance of Partilce detecotrs wr.t. to electron cooler	As of Yuris post in the elog the positions (Info from H. Weick):
89	Mon Apr 4 16:26:04 2022	Carsten	DAQ	Backup Harddisk /External Disk	Since we cannot write on lustre, as a temproal solution two RAID 1 (mirror) USB hard disks with cpacity 6 TB each are installed.
91	Mon Apr 4 19:05:57 2022	Carsten	DAQ	Cooler Frequency Signals Ion current not connected until now	Up to now the signals for Ion Current Cooler elctron current
103	Tue Apr 5 23:07:34 2022	Carsten	Accelerator	229Th89+ identification after re-tuning of the ESR	The ESR was retuned this aftenoon since the it was unclear if we still sit the 229Th89+ line.
104	Tue Apr 5 23:55:11 2022	Carsten	Runs	Long time measurment with NTCAP	Settings: Center: 2242.5MHz RefLevel: -25dB
123	Thu Apr 7 03:09:36 2022	Carsten	DAQ	NTCAP running since 02:40
173	Sat Apr 9 02:55:38 2022	Carsten	Accelerator	Kühlerausfall und Gründe dazu	Wir hatten heute Abend eine Kühlerausfall, der uns mehrere Stunden beschäftigt hat, weil gem. Anzeige in Device Control kein
175	Sat Apr 9 03:46:31 2022	Carsten	Accelerator	Slits in TE line	Changed GTEDSAH Rechts to 10mm
176	Sat Apr 9 03:57:10 2022	Carsten	Accelerator	New Cooler voltage after the crash of the cooler	After the restart of the cooler the Ohmlabs divider showed a voltage 16V lower than before. This could also be seen as a slight shift
177	Sat Apr 9 04:01:35 2022	Carsten		2nd DAQ	Switched the CAEN TDC back on and changed the threshoolds for the ADC to:
179	Sat Apr 9 05:00:11 2022	Carsten	General	Draft Docs and cheat sheet	Please check the attached files, and correct or enhance them.
