Absolute photometry of pulsed intense fluxes of ultrasoft X-ray radiation

Abstract

A method of absolute intensity measurement of intensive impulse fluxes has been described. Method and primary absolute detector device - photoionization quantometer - are based on fundamental cross sections of photoionization and ionization by electron impact. New soft X-ray optic elements - multilayer mirrors (MLM) were tested and used for constructing a 10-channel spectroanalyzer (polychromator) for photon energy range 0.1-1.0 keV. Results of polychromator using at "Angara-5-1" installation are presented.
