The high sensitivity of traditional diagnostic methods hinders their application in inertial confinement fusion with the pulsed radiation power of target plasma being as high as 1013–1014 W. Different methods of attenuating the incident radiation flux either alter its characteristics or are too complicated. The results of tests of a new detector, where quartz glass is used as a sensing element, at the Angara-5-1 facility are presented. It is demonstrated experimentally that the detector sensitivity is ~2 V/(MW cm2) and the time resolution is ~1 ns. The mechanism of formation of the response signal, where the temperature of electrons produced under irradiation plays a significant part, is discussed. [ABSTRACT FROM AUTHOR]

The set of diagnostic techniques used at the Angara-5-1 facility that make it possible to study the processes which accompany the ultrafast current-driven implosion of liners is described. This set includes electric methods and methods for the detection of various radiations. The liner-plasma shapes are visualized by detecting the intrinsic liner radiation in various wavelength ranges and actively probing liners in the visible and X-ray regions. Examples of the results of studying the current-driven implosion of cylindrical arrays of tungsten wires at the Angara-5-1 facility are presented. [ABSTRACT FROM AUTHOR]
