| Research Abstract |
We have developed APD (Avalanche PhotoDiode) photon counting system for soft x-ray experiments at SPring-8. APD detectors for hard x-ray are widely used at synchrotron radiation facilities taking advantages of the high time-resolution and the wide dynamic-range. However, the present APD doesn't cover soft x-ray region. The purpose is to develop a new APD detector especially for soft x-rays, where the sensor has to be installed in ultra high vacuum. The lower noise level and the higher gain are required as the technical subject to achieve in the development. We have succeeded in detecting the soft x-rays and have observed x-ray bunch structures of synchrotron radiation, and a soft x-ray magnetic circular dichroism measurement.
