METHOD TO MEASURE SPATIAL DISTRIBUTION OF ION TEMPERATURE OF HYDROGEN PLASM

摘要

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 E_i 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 E_i. 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 T_ion in this LMA. Then they produce values T_ion(j) for j local areas of measurement and dependence T_ion(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.;3 dwg
