Prospects for the Use of Gamma-Ray Spectrometric Diagnostics of Fast Particles at the TRT Tokamak

A project of a gamma-ray spectrometric system for diagnosing fast particles in the TRT tokamak plasma is described. The organizational concept of gamma spectrometric measurements is proposed. Preliminary results of calculating the intensities of gamma ray lines of hydrogen, deuterium, and deuterium–tritium plasmas are presented, which demonstrate the possibility of obtaining information about the energy and spatial distribution of fast ions with a time resolution of 1–10 s when using a multidetector system. Runaway electrons can be observed by hard X-ray emission from the tokamak plasma in the megaelectronvolt range.
