摘要：

A modification of the neutron activation method for the diagnostics of deuterium-tritium plasma of powerful pulsed fusion facilities is proposed. The method allows one to determine the effective plasma ion temperature by width of the spectral distribution of generated DT neutrons. The physical basis of the method and conditions for its implementation are described and methods for the calibration of measuring channels sensitivity are considered.
