Abstract
The construction and calibration of a multichannel neutral particle-energy analyzer applicable for the study of the heating of the ion component of a plasma in processes of brief duration are described. The analyzer allows one to obtain nine points in the energy distribution under study in one cycle of operation of the experimental apparatus, which makes it possible to exclude the effect of non-duplication of the process on the results obtained. The instrument consists of a gas stripping chamber and a nine-channel electrostatic ion-energy analyzer based on a flat capacitor with the angle of entrance of the particles into the analyzing field θ = 45 °. Results are given on the calibration of the stripping chamber for hydrogen atoms H ° in the energy range ɛ = (0.3–10) keV and for He ° atoms in the range ɛ = (1–10) keV. Air, hydrogen, and helium were used as the conversion target gases.
