Abstract

In the paper, the problem of measuring the ion temperature Ti in deuterium–tritium plasma is considered. It is proposed to use a gas proportional counter operating in the current mode to measure Ti. When neutrons interact with the gas environment of the counter, alpha particles and residual nuclei are generated creating ionization tracks. Only the tracks that form the braking peak of ionization upon stopping due to the so-called Bragg effect are selected. In order to obtain the neutron-energy distribution, it is necessary to select the ionization tracks characterized by two braking peaks: one from the alpha particle and the other from the residual nucleus. This choice makes it possible to exclude the so-called “wall effect,” that is, events that are not fully covered by the counter volume. It is shown that this type of neutron detector allows for an energy resolution of about 10–3.
