Abstract

VUV emission model of a hygrogen plasma with oxygen impurity (T e=tens of eV,n e ≈ 1014–1016 cm−3,nimp=1–3 % ne) is constructed in order to judge different possibilities of plasma diagnostics (especiallyT e measurements) in the REBEX experiments. Two sets of calculations based on the nonstationary corona model are performed: time dependent continuous and line spectra in the range 5 eV—5 keV in the constantT e approximation (discussion ofT e measurements by the filter-method) and time dependent intensities of selected spectral lines (2s-2p type) of ionsO 2+–O5+ at variableT e (including plasma heating by REB and radiative cooling). A possibility of plasma energy content determination from radiation losses is shown.
