Energy resolved soft X-ray imaging for the measurements of local distortion of distribution function

In the Large Helical Device, we have constructed a diagnostic system for simultaneous achievement of imaging and photoncounting in high temperature plasmas by using dual soft X-ray CCD cameras and several filters with different cutoff energies. In a long pulse discharge, peak of the image tend to be shifted outward as the energy range becomes higher. The energy spectrum has been measured at the same time, which leads to the future measurement of locally distorted distribution function.
