Paper Abstract

This paper presents the results of development of X-ray streak cameras, calibration test beds and methods for calibration of streak cameras and elements of X-ray optical schemes, procedures for recording a number of plasma parameters. We describe methods for streak photography of laser-produced plasma X-ray emission in experiments with various targets conducted on the facilities ISKRA-4 and ISKRA-5. These methods allow to make time-resolved records of the continuous plasma X-ray emission in various spectral ranges, to sweep in time line X-ray emission, to make simultaneous records of several plasma images in various spectral ranges, to make simultaneous records of several cross-sections of an object with subsequent reconstruction of a number of its two-dimensional images at various moments of time with ps time resolution. By using these methods it is possible to control target irradiation uniformity in time, to study the dynamics of the microsphere implosion and outwardly blowing plasma corona, to determine the lifetime of the imploded core, to investigate the time evolution of electron temperature and to study the mixing processes of materials of various densities in multilayered targets.
