New holographic grating devices for hot plasma diagnostics. I. Stigmatic properties of spherical holographic grating

Abstract

In laser induced confinement fusion or in ion driven fusion the understanding of the physical process taking place in the plasma atmosphere surrounding the target is extremely important. Plasma diagnostics requires line ratios and line broadening measurements to be made at very short wavelengths. The author presents the design of stigmatic normal and grazing incidence devices fitted with spherical holographic gratings.
