I just published three scintillation-probe related posts at www.diyPhysics.com.
First is on the construction of a very simple low-pass filter to interface commercial PMT amplifiers/scintillation processors to the PRA (“Pulse Recorder and Analyser”) software MCA:
Second is on the construction of a simple Bias-T for PMT scintillation probes: http://www.diyphysics.com/2012/02/20/simple-d-i-y-bias-t-for-scintillation-probes-with-single-connector/
Last is on how to connect to surplus Scionix miniature scintillation probes:
