63	Thu Mar 19 09:43:28 2020	Laszlo	General	Status of the ESR	After two days of tuning the beam, yesterday evening (~8pm), it was found out that within one ESR pattern using the new control system
65	Thu Mar 19 19:14:40 2020	Laszlo	General	primary beam measurement	Now our aim is to decelerate the primary beam (naked 124Xe) down to 10MeV/u. At this energy we can test our detectors and that how the

67	Fri Mar 20 01:11:58 2020	Laszlo	General	Target - beam jntersection	We have managed to find the target position with the beam by looking at the xray spectra. The trick was that at 10mev we

70	Fri Mar 20 01:36:48 2020	Laszlo	General	124Xe primary beam at 10Mev TargetON	We didmt see any effect on the lifetime if the target is switched on. It is because we use only hydrogen target (but why
84	Fri Mar 20 16:48:00 2020	Laszlo	General	flipped Si shaper output in x and y	Yesterday evening we have found out that the energy signals from the silicon are negative --> wrong polarity of the shapers was chosen
89	Fri Mar 20 22:51:36 2020	Laszlo	General	Target on signal change	From the previous settings: JetOn mashine number 11
90	Fri Mar 20 22:54:30 2020	Laszlo	General	First view of the beam	Intensity from Sis 1.7E9 The intensity is too.low at ESR to be visible. However we could.catch it somehow with Shottky
91	Fri Mar 20 23:43:26 2020	Laszlo	General	Vacuum while moving in the detector at yesterday evening	Vacuum before DSSSD movement: 1.5844E-11 Top value after movement: 3.64378E-11

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
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.
