X-RAY SOURCE, AND FLUORESCENT X-RAY ANALYZING DEVICE

摘要

The present invention relates to an X-ray source for emitting a characteristic X-ray and a fluorescent X-ray analyzing apparatus using the X-ray source. A secondary target (119) is arranged in superposition on a primary target (118). An electron beam (115) generated by an electron gun (114) enters the primary target (118), which passes and emits a continuous X-ray. The secondary target (119) transmits and emits a characteristic X-ray (121) excited by the continuous X-ray emitted from the primary target (118). The primary target (118) and the secondary target (119) are superposed one on the other, so that the continuous X-ray emitted from the primary target (118) efficiently excites the secondary target (119) thereby to efficiently generate the characteristic X-ray (121).
