Title: X-ray generation detector
Inventor: MINAMI TAKAO
IPC: G01T1/17
Filed: 1997-02-05
Abstract: PROBLEM TO BE SOLVED: To detect each X ray even if a plurality of X rays enter within an extremely close time range and to detect X rays even with a low energy by reducing time required for detecting X rays after their incidence regarding the detection of the generation of X rays at an X-ray measuring device.

When X rays with a high energy enter, they can be detected quickly by the waveform-shaping circuit 20 with a shorter shaping time constant. On the other hand, when X rays with a low energy enter, they can be detected by the waveform-shaping circuit 21 with a longer shaping time constant. The waveform-shaping circuit 21 is reset based on a detection signal from a logic OR circuit 24 and can prepare for a next step input, thus reducing time required for detecting the X rays after they enter.
