Laboratory Wide Dynamic Range Gamma-Ray Calibration Facility

AbstraktAbstract

A number of radiation-related applications in space such as γ-ray spectroscopy demand a flexible and wide-range γ-ray source which can serve as a calibrating and testing station for γ-ray detectors and γ-ray sensitive devices. The technical objective of this project was to design and build such a wide energy γ-ray source for calibration γ-ray detectors. The emphasis was put on satisfying the needs of BepiColombo (BC) and SoIar Orbiter (SolO) missions. The source should generate both primary γ-rays via the radiative capture of thermal neutrons (n,) on a selectable target and secondary gamma-rays by the inelastic scattering of fast neutrons (n, n' ). The range of gamma ray lines emitted from the target should cover the entire nuclear transition region (50 keV to 10 MeV), making it possible to calibrate a γ-ray detection system in one measurement.
