Neutral beam (NB) heating is one of the effective auxiliary heating means in the research on magntically controllable nuclear fusion, for which an 1MW NBI (netural beam injection) system has been constructing. As an integral part of the system, a calorimeter target was designed to measure the NB power and power density distribution on NB cross-section. Introduces the principle of measurement and construction features of the calorimeter target, with the NBI system briefly (described.)
