The + polarity test input is derived from tee'd output from BNC PB-4 and EG&G Ortec 433 Sum & Invert - physically moving the cabling and connectors between these two points changed tail pulse amplitude or produced a transient (non-tail) pulse with duration ~ 100ns. Not clear which cable or connector is the issue (all cables and connectors were individually replaced) but output amplitude currently correct so will proceed. 11.22 DAQ starts File May2017/R4 Pulser walkthough BNC PB-4 settings Amplitude 90,000 - 10,000 @ 10,000 step x5 attenuator IN t_r 50ns, tau_d 50us polarity - rate ~250Hz delay MIN, tail pulse ASIC settings 2017Mar27-16.12.39 See attachment 14 11.28 DAQ starts File May2017/R5 Pulser walkthough BNC PB-4 settings Amplitude 12,000 - 2,000 @ 2,000 step x5 attenuator IN t_r 50ns, tau_d 50us polarity - rate ~250Hz delay MIN, tail pulse ASIC settings 2017Mar27-16.12.39 See attachment 15 17.25 E17/F11 ambient temperature +24.7 deg C, RH 28.1%, d.p. +5.0 deg C Julabo FL11006 set point +20 deg C, actual +20.0 deg C, water level OK (c. 65%) 17.32 Detector biases & leakage currents OK - see attachments 16-17 FEE64 Temperatures OK - see attachment 18 17.40 DAQ starts File May2017/R6 Continuing DAQ test BNC PB-4 settings Amplitude 90,000 x5 attenuator IN t_r 50ns, tau_d 50us polarity - frequency 25Hz range delay MIN, tail pulse ASIC settings 2017Mar27-16.12.39 slow comparator 0x20 Encoding: HTML ELCode plain Suppress Email notification
