222	Fri Mar 10 22:40:00 2023	IP	Other	General	Ge - the rate is higher	the rates of detectors are still a bit higher
223	Fri Mar 10 23:27:51 2023	IP	Problems	Software	run 53 - stopped	the daq crashed at 22:43 -- problem with Local Filter the run 53 - stopped
224	Fri Mar 10 23:29:43 2023	IP	Problem Fixed	Software	new run 54	the daq resolved at 23:15 start new run: run 54

226	Sat Mar 11 00:05:06 2023	IP	Runs	General	run 54 - stopped	run 54 - stopped due to change the distance in plunger Run number: 54 Start
227	Sat Mar 11 00:34:51 2023	BS	Runs	General	Run 55 Started New Distance 500 um	Run 55 Started New Distance 500 um
228	Sat Mar 11 09:29:48 2023	EG	Other		current exeriment parameters as requested in the manual for shifters	41_ge_single_theta 101,117,143 looks ok. No peakdeformation of 511, other gammas FWHM around half of that of511 - ok
230	Sat Mar 11 11:39:55 2023	EG	Problems		Buffers clearing	at 11:34:50 sek on 11 march a spike in counting rate of some Ge detectors is observed. Buffers not cleared properly?
231	Sat Mar 11 12:42:42 2023	EG	Other		Beam intensity reduction	Again beam intensity gradually increased reaching 2.4 kHz ontotal rate EAGLE_0 ch4. Beam intensity reduction requested. 1.8 kHz
232	Sat Mar 11 14:15:55 2023	EG	Runs		Beam intensity rapid increase	14:12 beam intensity instability. Rapid increase of beam intensity - twice the previous value. Returned to normal after 4 minutes.
233	Sat Mar 11 14:42:28 2023	EG	Runs		Beam instabilities	Large beam intensity instabilities from 14:10 till 14:40. Beam intensity reduction requested. CH4 on Total rate EAGLE_0 returned
