Gamma-ray spectrometry provides diagnostics of fast ion behavior in plasmas of large tokamaks. Information acquiring with the gamma-ray diagnostics gives possibility to identify and distinguish simultaneously presence of fast alpha-particles and other ions (H, D, T, ³He), to obtain its relative densities and also to perform tomographic radial profile reconstruction of the gamma-emission sources.
