Investigation of radiative properties of plasma objects by methods of X-ray image spectroscopy

Emergence of a new class of x ray spectral devices, namely, image x ray spectroscopy devices, comprising high-luminosity spectrographs with spherical crystals, transmitting diffractional obscure lattices, and multilayer Bragg-Fresnel lenses, expands substantially the capabilities of high-temperature plasma experimental spectroscopy. It is shown that application of these devices in plasma diagnostics gives information about one- and two-dimensional spatial distribution of parameters of both nonhomogeneous plasma microobjects (micropinches, dense laser plasma regions) and extended plasma sources in the regions of their low luminosity (scattering laser plasma at large distances from the target). 61 refs., 23 figs., 7 tabs
