SCANNING ENERGY ANALYZER OF CHARGE-EXCHANGE ATOMS

The construction, operation principle, and parameters of multichannel scanning energy analyzer of charge exchange atoms are discussed. The a nalyzer is used to measure the splashing ion angular distribution and energy spectra, the ions being produced in a gas dynamic plasma trap ( GDCS) during the injection of powerful atomic hydrogen beam into preli minary produced plasma with density n similar or equal to 5 x 10(13) c m(-3) [1,2]. The parameters of the hydrogen beam are as follows: parti cle energy - 50 keV, equivalent current - 250 A, pulse duration - 1 ms . The device can be also used for measurements of energy spectra of at omic and charged particle beams in plasma diagnostics, beam physics, a nd physics of atomic collisions.
