Abstract
We found that the CCDs onbord Hayabusa XRS has degradated more or less by the radiation. This has caused not achiving the energy resolution of prelaunch.
So we have to develop onbord processing method for future X-ray fluorescence spectrometer.
In this presentation, we evaluated how the Hotpixel had worsen the energy resolution in Hayabusa by using 'CCD-image' data taken in cruising phase and in laboratory.
We present the results of another processing method for future asteroids exploration.
