摘要：

The authors measure the absolute spectral sensitivity of an x-ray image converter (XIC) with a beryllium window and a microchannel plate as a converting and amplifying element in the energy range of x-ray quanta of 7 to 20 keV. The measurements are performed in the synchrotron-radiation channel of the VEPP-3M accumulator of the Institute of Nuclear Physics of the Siberian Division of the Academy of Sciences of the USSR. It is shown that in the indicated energy range the ratio of the number of photons in the blue region of the spectrum at the exit from the XIC to the number of x-ray quanta at the entrance increases from 1200 to 2200 photons per quantum. The sensitivity variation over the working field of the XIC is studied.
