NEW OPTICAL METHODS FOR SHORT-WAVELENGTH HOT PLASMA DIAGNOSTICS

We have developed new types of experimental methods for high-temperatu re plasma diagnostics based on both glass capillary converters (GCCs) and multilayer mirrors (MLMs), where the optical GCC device provides g uiding, focusing; and polarization analysis of short wavelength radiat ion with a large bandwidth, and the MLM elements are used for dispersi ng, focusing, and polarization sensitive studies of radiation within a narrow bandwidth. In particular, we report here for the first time, t o the best of our knowledge, the development and testing of such new o ptical diagnostic devices for: (i) pinhole chamber with GCC, (ii) GCC converter for time-resolved x-ray measurements, (iii) polarimeters-spe ctrometers with GCC and MLM for measurements of polarization and spect ral characteristics of short wavelength radiation, and (iv) high sensi tivity extreme ultraviolet spectrometers.
