Abstract
The paper is devoted to an investigation of the formation and spreading of an inhomogeneous dense plasma heated by high-power laser radiation. The present status of the experimental and theoretical research in this field is analyzed. The “Kal'-mar” facility is used to study the dynamics of the plasma corona (electron density ne ~ 1018–1020 cm-3), the law of motion of the critical (ne ~ 1021 cm-3) region of the plasma is established, and the dependence of the rate of compression of the shell targets on the initial parameters is determined. The electron temperature of the corona is measured with high temporal resolution in the course of the compression. A jetlike expansion of the “fast” ions is observed and investigated.
