New optical methods for short wavelength hot plasma diagnostics

Abstract

We have developed new types of experimental methods for high-temperature plasma diagnostics based on both glass capillary converters (GCCs) and multilayer mirrors (MLMs), where the optical GCC device provides guiding, focusing, and polarization analysis of short wavelength radiation with a large bandwidth, and the MLM elements are used for dispersing, focusing, and polarization sensitive studies of radiation within a narrow bandwidth. In particular, we report here for the first time, to the best of our knowledge, the development and testing of such new optical diagnostic devices for: (i) pinhole chamber with GCC, (ii) GCC converter for time-resolved x-ray measurements, (iii) polarimeters–spectrometers with GCC and MLM for measurements of polarization and spectral characteristics of short wavelength radiation, and (iv) high sensitivity extreme ultraviolet spectrometers.
