MIT fusion γ‐ray diagnostic development

In conjunction with {gamma}-ray diagnostic development for the NOVA Upgrade and Alcator C-MOD experiments, we have assembled a comprehensive set of absolutely calibrated {gamma}-ray sources and several {gamma}-ray detectors. These tools will be used in characterizing and calibrating new {gamma}-ray diagnostic systems as they are assembled. The {gamma}-ray sources comprise both radioisotopes and nuclear reactions. The latter are generated in the MIT Cockcroft--Walton fusion-product generator. The detectors include several standard'' NaI(Tl) scintillators and a high-resolution germanium detector. This paper briefly discusses the diagnostics planned for NOVA Upgrade and Alcator C-MOD. In addition it describes the {gamma}-ray sources and detector characterizations we have performed in the laboratory.
