Automated response matching for organic scintillation detector arrays

Abstract

This paper identifies a digitizer technology with unique features that facilitates feedback control for the realization of a software-based technique for automatically calibrating detector responses. Three such auto-calibration techniques have been developed and are described along with an explanation of the main configuration settings and potential pitfalls. Automating this process increases repeatability, simplifies user operation, enables remote and periodic system calibration where consistency across detectors' responses are critical.

Simultaneous, Robot-Compatible γ-Ray Spectroscopy and Imaging of an Operating Nuclear Reactor

“…The radiation detection analysis hardware utilised for this research is a quad-channel Mixed Field Analyser (MFA, Hybrid Instruments Ltd., UK) [12]. It provides 12-bit sampling resolution at a rate of 500 MSa/s, and has neutron-γ discrimination and spectroscopic capabilities, as well as Transistor-Transistor-Logic (TTL) outputs for counting purposes [13], [14]. For this application, part of this commercial hardware has been ported into a bespoke enclosure to contain the instrumentation's electronics, with passive cooling and 12 V DC power supply.…”
