Spectroscopy of Multicharged Ions in Laboratory Plasma
Spectra of multicharged ions are now widely investigated both in laboratory and astrojihysical plasmas. The typical temperature values of such plasmas are from about 200 eV up to 2 keV and even higher (i.e. (2+20) 106K). The sources of laboratory plasma which were used in spectroscopy are laser produced plasmas, vacuum sparks, theta-pinch devices, tokamaks and some others.Data used in this report concern the first two sources. As for astrophysics, the solar corona is, in fact, a unique object, for which good line spectra are obtained in the X-ray region. The study of the line spectra of non-solar X-ray sources is extremely difficult due to small flux values. However, it seems very probable that the first such spectra are to be obtained with the large X-ray telescope of the USA orbiting satellite HEAO-B which is to be launched this autumn.
