Abstract
Results are presented from measurements of the energy spectra and fluxes of the escaping charged fusion products and fluxes of fusion neutrons in ohmic regimes of the T-10 tokamak. The central temperature of the plasma ions is determined from the broadening of the energy spectra of thermonuclear protons and tritons. The ion temperature profile is evaluated from the dependence of the fluxes of charged fusion products on the radial plasma shift. It is proposed to use a single spectrometric detector with several collimators and slowing-down foils to measure the distribution of charged fusion products over pitch angles, which permits the determination of the ion temperature profile in a single shot. The feasibility of the method proposed is proved experimentally.
