DECal, a Python tool for the efficiency calculation of thermal neutron detectors based on thin-film converters

Abstract: The Detector Efficiency Calculator (DECal) is a series of Python functions and tools designed to analytically calculate, visualise and optimise the detection efficiency of thermal neutron detectors, which are based on thin-film converters. The implementation presented in this article concerns 10B-based detectors in particular. The code can be run via a graphical user interface, as well as via the command line. The source code is openly available to interested users via a GitHub repository.
