摘要：

A new high-intensity x-ray source equipped with an electron gun for low tube-voltage operation has been developed. Lowering the tube voltage is highly effective in eliminating higher order harmonics from the monochromator, which degrade the spectrum in extended x-ray absorption fine structure measurements. The present x-ray generator provides a narrow line focal spot with a high tube current of 900 mA even at a low tube voltage of 20 kV. Extremely intense monochromatic x-rays, which are completely free from higher order reflections, are now available in a laboratory.
