Low-energy ion measurements by means of CR-39 nuclear track detectors

The paper presents an additional acceleration system, used to shift up an i on energy spectrum by 20 keV, and some examples of the ion parabolas regist ered by means of a Thomson-type spectrometer within the rod plasma injector (RPI-60) facility, designed for plasma physics and application studies. Th e use of the described acceleration system and CR-39 track detectors has en abled the registration of ions of energy above 20 keV to be performed. It m ade possible to measure the ion (e.g. deuteron) energy spectrum more exactl y in the low-energy range, what is important for the determination of ion e mission characteristics.
