106	Sat Mar 21 06:02:22 2020	Tino, Oliver	General	Detector filling	Run stopped for detector fillings
115	Sat Mar 21 10:20:27 2020	Ragan, Alex	General	Target LN2	The LN2 Dewar on the ESR roof has been refilled.
119	Sat Mar 21 11:30:04 2020	Laszlo	General	MWPC movement	now we try to move the capture detector (MWPC in the 1. dipol before our Si setup) inside the ring while the DAQ was ON
122	Sat Mar 21 12:02:57 2020	Ragan, Laszlo	General	run entry - run061	12:02 pm - scapper is taken out completely open file : runstart061
123	Sat Mar 21 12:06:50 2020	Laszlo	General	run61 - SCRAPER moved out	we want to see any change on the Silicon count rate, because we will have now also Rutherford scattering.
125	Sat Mar 21 12:32:00 2020	Laszlo	General	Estimated target thickness	Target thickness must be like 5mm (was measured with a moving thin wire) The beam thickness is small because of the
126	Sat Mar 21 12:42:21 2020	Ragan	General	Entry to ESR for MCP detector	Pierre Michel and Laszlo go inside the ESR for switching on the MCP detector so that the photons from the gas jet and secondary
130	Sat Mar 21 14:52:05 2020	Laszlo	General	target optimization	previous position of the beam at target was -3mm (for the night position) max. intensity position of the beam at target
133	Sat Mar 21 15:26:49 2020	Laszlo	General	SCRAPER is ON use again	Yuri puts back the scraper (Egelhof 1 - GE01DD1IG) into position = +19. (where it was in the evening)
134	Sat Mar 21 15:30:34 2020	Sergiy	General	go into the ESR	We are going into the ESR to check the electronics. Use calibration sources (133Ba etc).
135	Sat Mar 21 17:21:57 2020	Laszlo	General	new Target density	Ulli and Nikos managed to set the target density to ~7E13 at 51K temperature
138	Sat Mar 21 17:34:10 2020	Sergiy	General	Recoils	We started recording the data from the recoils using the MCP from Pierre-Michael's experiment.
140	Sat Mar 21 18:13:22 2020	Shahab	General	rough comparison gas target off and on	rough comparison of life time at 10 MeV/u when target off with on. more noise in background means weaker signal.
151	Sat Mar 21 23:07:00 2020	Laszlo	General	1672. MCP file was (recoils) was not closed	1672. MCP file was (recoils) was not closed when we refilled the Xrays and did the cable change of 90 and 145 xrays
177	Sun Mar 22 10:05:37 2020	Esther, Ragan	General	run entry - run079	The intensity of beam from SIS is less due to some issues with UNILAc.
179	Sun Mar 22 10:28:27 2020	Esther, Ragan	General	run entry - run079	The problem at UNILAC seems to have solved itself. Intensity is returning to normal.
183	Sun Mar 22 12:01:44 2020	Esther, Ragan	General	Vacuum problem with SIS	There is some problem with the vacuum in SIS and thus data recording is stopped.
186	Sun Mar 22 12:53:43 2020	Laszlo	General	quick summary for the 118Te overnight measurement	Quoting Yury: "The count rate is very low. We estimate that we store about 10^4 118Te particles
188	Sun Mar 22 13:33:19 2020	Laszlo	General	2nd storage of MCP data	I made a backup for the MCP data on my own GSI laptop. Looking for better solution... the original "fresh" files stored at litv-exp@lxg1299:/data.local2/hillenbrand/Laszlo/
191	Sun Mar 22 14:58:59 2020	Laszlo	General	dropping density of Gasjet	after like 20min run, the density of the gasjet already dropped from 10^14 to 8.7*10^13. Now it seems to remain in that value
