X-ray spectrograph on the basis of a multilayer cylindrical mirror with variable period

This work is a description of a wide-range X-ray spectrograph design for fast physical processes in the hot non-equilibrium plasma investigation. Two ways of registration range broadening in the offered scheme are simultaneously used: curving of a mirror and creation of a multilayer structure period gradient. Computation performances of spectrograph and multilayer mirror for prospective geometry of measurements are explicitly described: structure, energy registration range, energy resolution, luminosity and line form on the detector. rror is supposed to be produced at BINP (Novosibirsk, Russia), where the production process of cylindrically curved multilayer mirrors is organized and there is an experience of manufacturing mirrors with variable period. ven spectrograph is supposed to be used for spectral X-ray measurements of hot non-equilibrium plasma at VNIIEF impulse facilities: ISKRA-5, plasma focuses and devices with plasma magnetic compression.
