FIELD: instrumentation.
SUBSTANCE: to each registered atom an electric pulse at an analyser outlet corresponds, and simultaneously photons are registered with a spectral selective device (SSD), having a common input collimator with the analyser. At the same time atoms are registered with energy Ei by i channel of the analyser, and photons are registered with wave length λ0-Δλ by i channel of the SSD, where λ0 - wave length of a hydrogen line, emitted by a dormant atom, and Δλ - wave length shift specified by Doppler effect for energy Ei. Occurred electric pulses from the outlet of a coincidence detector are sent to a pulse counter and by the ratio of quantity of pulses registered in different channels of the analyser, they determine energy distribution of recharging atoms and accordingly ion temperature Tion in this LMA. Then they produce values Tion(j) for j local areas of measurement and dependence Tion(L), where L - coordinate along the observation line, i.e. spatial distribution of ion temperature.
EFFECT: provision of possibility of measurements without use of probing atom bundles, increased validity and accuracy of measurements.
