Abstract

Gas-filled proportional counters perform well as neutron spectrometers in the energy region from a few tens of keV up to about 1.5 MeV. Unfortunately, gamma rays also generate signals in these detectors. It is possible in principle to distinguish the two types of event via the rise time of their respective signal pulses, but the data acquisition system needed for this is complex to assemble and adjust if one uses conventional modular analogue electronics.
In this work a digital sampling system, in conjunction with custom software, was used to measure and acquire amplitude and rise time data from type SP2 counters. The interpretation of the data was supported by a Monte Carlo calculation. The performance of the system is compared to that of a conventional 1-parameter analogue system, and the potential of the digital technique to supplant conventional methods is discussed.
