Av. Vodopyanov et al., Mirror-trapped plasma heated by high-power millimeter-wave radiation as anelectron-cyclotron-resonanse source of soft X-rays, JPN J A P 1, 40(2B), 2001, pp. 1016-1017
Soft X-ray line emission of pulse electron-cyclotron-resonance (ECR) discha
rge in Argon sustained by a powerful beam of millimeter waves in a mirror m
agnetic trap was investigated. An X-ray spectrum in the range of 6-17 nm ha
s been obtained, and the absolute spectral intensity of radiation in this r
ange has been determined. It was shown that such a discharge is an effectiv
e source of soft X-ray radiation with an approximately 10% conversion effic
iency of microwaves into X-rays and a spectral power maximum of 7.3 kW/nm a
t a wavelength of 9 nm.
