Abstract

The photon detection efficiency of a ceramic-channel electron multiplier (Ceratron) has been measured on an absolute scale from 20 to 78 Å using monochromatized synchrotron radiation. The measured efficiency was several percent at these wavelengths. Its wavelength dependence shows a gradually increasing trend for wavelengths longer than 28 Å. The efficiency showed two maxima at ~23 and 27 Å, which are presumed to originate from the O-K absorption and the Ti-L absorption, respectively. Optimization of the detection efficiency is discussed.
