156	Fri Apr 8 09:33:52 2022	Dayshift 1 8.4.2022		Reference Measurements	DAQ1: lxg1297:/data.local2/BeamTimeTh22/ DAQ2: lxg0155:/data.local2/E142/ LMD file name DAQ1:229Thor
155	Fri Apr 8 09:32:32 2022	Ragan	Runs	NTCAP stopped	Since there is no beam, NTCAP is stopped. Carrier Frequency: 242.2 M
154	Fri Apr 8 09:13:38 2022	Ragan, Danyal	Accelerator	No beam	Cathode is being changed at the ion source. So no beam for the moment.
153	Fri Apr 8 08:40:06 2022	Sebastian	DAQ	DAQ improvement	Concerning ID 146 a new histogram for accumulating data (no cleaning histograms) can be found under
152	Fri Apr 8 08:17:52 2022	Sebastian	Laser	Laser Ext Trig is working	We (Max, Kristian, Danyal, me) fixed the "external trigger" problem.
151	Fri Apr 8 06:53:29 2022	Ragan	Runs	NTCAP data taking	NTCAP is taking data since 07.04.2022 23:53:47 Carrier Frequency: 242.2 M
150	Fri Apr 8 05:46:35 2022	V. Hannen	Detectors	High background rate in Cu PMT points to light leak in ESR or active pressure gauge	The background rate of the Cu mirror PMT is only about 300 cps when the mirror is in the parking position but ca. 7000 cps when
149	Fri Apr 8 03:54:39 2022	Patrick	Laser	Q-switch window	The solution of increasing the Q-switch window from 2us to 5us described in [I]ID:148[/I] fulfills its purpose, but the window is unstable.
148	Fri Apr 8 02:14:05 2022	Wilfried	Laser	Laser timings adjusted	Since we use the middle window as a reference for the laser pulse timing, the fact that the window is 2.25 m behind the target has
147	Fri Apr 8 01:48:57 2022	Patrick	DAQ	Bugged Trending plots?	The wavelengths/frequencies shown in the graph in the labview window do not match the wavelengths/frequencies in go4.
146	Fri Apr 8 01:18:51 2022	Ken Ueberholz	DAQ	TODO: DAQ improvements	For somebody who knows the DAQ1 code: Go4 resets the histograms with each laser step. Can there be additional histograms where
145	Fri Apr 8 00:06:37 2022	Patrick	Laser	Connection to the laser pc	To login to the laser pc use the command xfreerdp -g 1920x1080 -u atplaser atppc023.campus.gsi.de
144	Thu Apr 7 22:18:06 2022	Night shift 7.4-8.4		Next scans	DAQ1: lxg1927:/data.local2/BeamTimeTh22/ DAQ2: lxg0155:/data.local2/E142/ LMD file name DAQ1:229Thor
143	Thu Apr 7 19:13:26 2022	Konstantin, Patrick	Calibration	How to find the correct laser position	In order to achieve the correct laser ion beam superposition one needs to do the following steps:
142	Thu Apr 7 16:50:22 2022	Konstantin	Calibration	Spacial laser-ion overlap	Laser-ion-beam overlap was achieved after measuring the ion beam positions (compare [URL=https://elog.gsi.de/esr/E142/83]Entry
141	Thu Apr 7 16:45:10 2022		Detectors	Detector distances	Relativ distances of the detector
140	Thu Apr 7 15:18:25 2022	Danyal & Sebastian	DAQ	DAQ channels	We checked again the cables for both DAQs (on Carsten's kind request)
139	Thu Apr 7 14:13:27 2022	Danyal	Detectors	new PMT south	I have replaced the PMT south (looks at the gas target). in the hope that this will produce less dark
138	Thu Apr 7 14:04:36 2022	Paul Indelicato	General	no beam until 17:00	10:10 There is a problem with the UNILAC. The repair will take several hours. (4 hrs?)
137	Thu Apr 7 14:01:22 2022	Sebastian, Max	Detectors	Mesytec reset	The Mesytec crate was turned off and on again. It is again possible to communicate with
