Abstract

The possibility of measuring pulsed X-ray spectra using a set of filter pairs including diffraction filters made of mosaic crystals of pyrolytic graphite (MCPG) and carbon attenuators with an equivalent value of the mass length is shown. The proposed spectral selection scheme is an alternative to broadband spectrometry with differential Ross filters used in the study of high-temperature plasma spectra generated by powerful laser or electric current pulses. The main advantages of the proposed spectrometric method are the possibility of continuous tuning of the spectral band width and the average spectrum energy. The use of carbon filters also allows the complete elimination of the balancing errors in absorption spectra that occur when using the Ross filters.
