Abstract

A new approach to the technique of determining absolute intensity of radiation in the XUV by a rare-gas photoelectron counter is described. This method is applied satisfactorily in the region of photon energy above 40 eV where the method using rare-gas ionization chambers is hampered by technical difficulties. Two examples of application of this method, the determination of the spectral response of a monochromator by using synchrotron radiation in a region between 23 eV and 54 eV, and determination of intensities for the Lyman series of He ii emitted by a stationary high density plasma, are presented.
