Please check this. Night shift has used the count rates directly from the plots.

AIDA is still seeing "nothing" Liu changes the distance of the Al degrader from 13mm to 11mm. Syncronization: Difference of timestamps between AIDA and BIGRIPS observed on terminals remains constant. 6:40: BIGRIPS stop the run and they ar doing calibrations for 20-30 minutes.

The reason is not understood). Date: 30/03/2017 Stop: 03:27 BRIKEN run:003 AIDA Run:R16_21 BigRIPS run:145 (just started) Online not erased. Root file:170330_0216_0326_B003_Mg40.root (accumulated with previous root) Syncronization terminals on screenshots to compare with previous run. Due to the updates on each terminal are not with the same frequency it is hard to observe in the screenshots, but on live seems to be constant.

Just Start File. Root file: HISTOGRAMS NOT SAVED FOR THIS RUN Observation: AIDA recovered at 02:15 Synchronization plot not generated. Some screenshots rom terminals attached. AIDA terminal has additional messages and between both terminals (AIDA/BIGRIPS) there is a constant offset apparently.

39	Mon Jul 18 18:40:32 2016	A. Tarifeño-Saldivia and J. L. Tain	3He tubes - Testing
Test of individual 3He tubes The tests were done using the ATOMKI MCA and HV: ISEG NH204M Preamp: Mesytec MHV-16 (Unipolar IFIC) Amp: ORTEC671 (Gain=5x0.5,SHP=6us) Pulser: 10Hz-Clock + TC410A G&DG + BH-1 (tr=1us,tf=1ms,amp=0.7) Spectra measured with 1024 channels Counting time: 100s (UPC, RIKEN and ORNL 1") 120s (ORNL 2") Neutron source: 252Cf PE setup: 1 inches tubes were tested on the BELEN-20 PE matrix, while for 2 inches tubes a moderator was prepared using existing material (see attached figures). Attached a figure with a sample spectrum for each tube type and a compressed file with all the measured spectra in ASCII format. All the tubes performed correctly. The neutron signal is well separated from the noise. The RIKEN tubes have the highest gain. Gain in the UPC tubes is the lowest.

Adjustment of HV and PA gain We adjust the HV for each tube type and the gain of the preamplifier (PA) in order to have a similar signal amplitude for the 764keV peak in all of them. Because of the very different gain between tubes we are not able to combine in the same PA tubes from RIKEN and UPC, thus we have to go for 10 PA instead of 9: Settings: Preamp (type), Tube type, HV, Gain, height or 764keV pulse, pulse polarity PA1 (D), RIKEN, 1450V, LowGain, ~400mV, POS PA2 (D), RIKEN, 1450V, LowGain, ~400mV, POS PA3 (D), UPC, 1550V, HighGain, ~400mV, POS PA4 (D), UPC, 1550V, HighGain, ~400mV, POS PA5 (U), UPC, 1550V, HighGain, ~600mV, NEG PA6 (U), ORNL1, 1200V, LowGain, ~400mV, NEG PA7 (U), ORNL2, 1750V, LowGain, ~400mV, NEG PA8 (U), ORNL2, 1750V, LowGain, ~400mV, NEG PA9 (U), ORNL2, 1750V, LowGain, ~400mV, NEG PA10 (U), ORNL2, 1750V, LowGain, ~400mV, NEG We need to use two different pulse generators to adjust differently the pulse height of UPC tubes
