X-ray diagnostics for the measurements of a bremsstrahlung radiation spectra of the FT-2 tokamak plasma with a high photon counting rate

The paper presents a new X-ray diagnostic system installed on the FT-2 tokamak for high-temperature plasma bremsstrahlung radiation spectra measurements. The design and technical characteristics of the diagnostics are described. A significant increase in the counting rate is shown while maintaining the spectral resolution of the developed system compared to the industrial device.
