> Runs acquired in Jan-Feb 2020 > > Detector bias -50V > Bias applied to one strip only of B-grade silicon W1 > Triple alpha source P9 > 500 samples pre-trigger > 8096 total samples > > - Internal triggering from CAEN v1730B digitiser > R1,2,3 - Cooknell preamps, positive waveforms > R4 - Skipped > R5,6 - RAL108 preamps, positive waveforms > > - External trigger provided from Ortec TFA + CFD + Lecroy Level Adaptor > - 500 sample pre-trigger, but note trigger position in time now resents of dealay between signal and TFA+CFD trigger chain > R7,8 - RAL108 preamp, negative waveforms > > - CFD threshold potentiometer cleaned. Threshold likely changed > - Reduced samples to 4096 > R9 - RAL108 preamp, negative waveforms > > - TFA failed & replaced. New gain settings Fine MAX (12.5x), Coarse 2x > - Samples stil at 4096 > - Pre trigger window increased to 1000 > R10 - RAL108 preamp, negative waveforms > R11 - RAL108 preamp, negative waveforms with Cs-137 gamma source > R12 - RAL108 preamp, negative waveforms at -25V bias > R13 - RAL108 preamp, negative waveforms at -75V bias > R14 - RAL108 preamp, negative waveforms with neutron source > R15 - RAL108 preamp, negative waveforms, background run
