The intensity monitor (I

-detector) for incident X-rays consists of a semi-transmission-type proportional
counter with Be window on both side, and provides linearity of up to 1 million cps through combined use
with a high-speed electronic circuit. On the other hand, the intensity monitor (I-detector) for X-rays
transmitted through the sample employs a high-speed scintillation counter, and is capable of counting
X-rays with a high degree of detection efficiency over a broad range of energy levels.
