12	Thu Mar 3 17:21:26 2022	Rodolfo	Detectors	MgF2 Windows	New reentrance viewports made of MgF2 have been installed at the ESR "Optical Detection Region". In the middle the old window (also
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
27	Mon Mar 21 21:48:46 2022	Jan	DAQ	MesyTec Shaper Control	The MesyTec Shaper & Constant Fraction (MSCF) is used to process the PMT/det signals for the ADC in the second DAQ.
124	Thu Apr 7 03:44:21 2022	Patrick	DAQ	Measurement procedure	[U][B]Measurement procedure[/B][/U]
78	Sun Apr 3 12:31:10 2022	Rui-Jiu Chen, Yuri, Carsten, Ragan	Runs	Measurement of beam with different circles	Parameters of NTCAP: 1. IQ rate 20 MSamples/s	6x
86	Mon Apr 4 09:10:44 2022	Ragan, Yuri, Rui-Jiu	Runs	Measurement	NTCAP is taking data with the beam with a stop at manipulation 5 (taking all the fragments).
227	Thu Apr 14 10:57:11 2022	Carsten	Accelerator	Maintanence UNILAC / Op training	We had no beam since about 1000. Also, we are still trying to find out why we have such a low intensity in the expereimnt.
21	Fri Mar 18 16:51:27 2022	Carsten	DAQ	Main DAQ /MBS error	MBS error "TDC data ready wait" solved. Common stop trigger (20 kHz) was missing. (according to Sebastian)
90	Mon Apr 4 17:26:48 2022	Jan Glorius	DAQ	MSCF shaper settings	attached are the current shaper settings. list of currently connected channels:
92	Tue Apr 5 08:00:50 2022	Kristian & Sebastian	DAQ	MBS Channellist (so far)	MBS Channellist (time 5.4.2022) 0 Anode
191	Sun Apr 10 03:56:56 2022	V. Hannen	Detectors	Low rate in PMT South	PMT south shows a much lower count rate than observed in elog entry 170.
226	Thu Apr 14 08:41:42 2022	Carsten	Accelerator	Low intensity at the experiment after series of failures during the night	After the recovery from the failures during the night, we see much lower intensity at the experiment (measured with the particle
104	Tue Apr 5 23:55:11 2022	Carsten	Runs	Long time measurment with NTCAP	Settings: Center: 2242.5MHz RefLevel: -25dB
10	Fri Nov 19 15:50:44 2021	Rodolfo	Accelerator	Laser windows at E-Cooler side	New laser viewports have been installed at the E-Cooler side of the ESR.
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
118	Thu Apr 7 00:15:11 2022	Patrick	Laser	Laser timing adjusted	We have adjusted the laser timing using PMT-middle. Bunching freq. is 3.90362 MHz.
36	Tue Mar 29 12:01:08 2022	Rodolfo	Laser	Laser targets	I have installed two targets* (size: 2 inches) to monitor the position of the laser beam.
182	Sat Apr 9 06:42:23 2022	Kristian	Laser	Laser step size	We changed the laser step size to 0.002 nm which corresponds to 5.75 GHz.
220	Tue Apr 12 15:05:56 2022	Rodolfo	Laser	Laser status	We have checked the laser power at 14:15 * - Pump energy after Q-Ray @ 532nm: 559 mJ.
224	Wed Apr 13 15:41:29 2022	Rodolfo & Sarper	Laser	Laser status	We have checked the power of the laser and optimized it "a bit".
