The Spectrometric Monitor of the TRT-Tokamak Total Neutron Yield

The attainment of high power of fusion reactions resulting in a substantial neutron yield from the tokamak plasma is the key objective of the TRT project. Providing quantitative control of fusion power created in the course of the D–D and D–T reactions with time is thus a basic requirement for the TRT diagnostic complex. In the present work, we analyze specific properties of the neutron source in high-power deuterium and deuterium–tritium discharges. The modern means of monitoring and spectrometric measurements of fusion neutrons are reviewed. Problems of integration of the detector assemblies into the tokamak construction, along with future steps in neutron diagnostic development, are discussed.
