Paper Abstract

A dense jet of a plasma consisting of multiply charged ions was generated in the interaction of a laser plasma with a strong external axial magnetic field. It is shown that use of high- luminosity x-ray specroheliograph technique allows us to measure plasma emission spectra with 2-dimensional spatial resolution even in the cases when these spectra have a small intensity. The x-ray spectroscopy and interferometry methods are used to measure plasma parameters distributions. The dependencies of Ne(z) and Te(z) measured in this paper can be used to calculate the evolution of plasma ionization state during plasma expansion. The quasihomogeneous laser jet, which appears when a laser plasma interacts with an external magnetic field, can be used not only to form an active medium of a shortwavelength laser, but probably also to tackle the urgent problem of transport in a laser ion injector.
