Abstract. Remarkable progress has been reached in the development of intense radiation sources and new optical elements for the vacuum ultraviolet spectrum. This progress has served as the basis for the development of many promising practical applications: X-ray lithography, X-ray holography, microscopy, and so on. For development of this trend, in particular, to optimize the parameters of sources and select optical elements, high-quality quantitative (absolute) measurements of radiation characteristics are necessary. However, conducting such measurements in the vacuum ultraviolet range of the spectrum is a rather complex task. This is because in this spectral range, all substances exhibit high absorption, which varies greatly depending on wavelength. That’s why all emission detectors needs independent calibration against a reference source over the entire wavelength range, since their sensitivity depends on the properties and purity of the absorbing surface. The presented work shows the method of photometry of monochromatic radiation in the ultraviolet spectrum, using two instruments: a calibrated thermal column and a photoelectric multiplier, the window of which is covered with a thin layer of salicylic acid sodium.
Key words: photoelectric multiplier, thermal element, number of photons, luminescence.
