New experiment, all lasers on.
Set laser delays to 0
Set all scaling factors to 0.5 (inc. FSC)
Acquire data with QF scripter automatically changing the QF intensity every second - 1000 events/second, gaussian pulse (5 sec) - standard settings (FSC set to 400V), record 20k events. Record all HWA signals on all channels, FL in LOG.
Set FSC so that all H/W FSC signals are on scale.
Set events to record to 20k.
Record data with PMT volts from 0-1000 (25V increments) - PM for app to do this unattended (vchanger.exe)
Put data in sub folder labelled 'laser_on' and 'laser_off' and run R script (updated in 2022)- request via email.
