る。 Furthermore, the configuration shown in FIG. 3 shows the measurement point detection device according to the present invention, and the
A detection metal plate 10 that integrates first and second metals 8 and 9 as a sample is placed on top, and this XY table 4 is shaped like an arrow because the tips 12 of the microheads 11 are connected to each other. It has a configuration that allows slight movement in the direction of A. Furthermore, the first and second metals are made of different metals, the first metal 8 being aluminum which hardly generates fluorescent X-rays, and the second metal being made of aluminum which generates fluorescent X-rays. Therefore, when the detection metal plate 10 is irradiated with an X-ray beam via the collimator 3 , as shown in FIG. The position (in the feed amount of the XY stage) is the boundary position between the first and second metals 8 and 9,
It can be seen that this is the irradiation position of fluorescent X-rays.
