Outline of Final Research Achievements

Toward the realization of the "backside illuminated type CMOS detector" necessary for constructing a "photon-counting imaging type" solar X-ray telescope capable of directly observing the particle acceleration region considered to be present in the solar corona, we performed a study to estimate the performance required for this detector from previous observations. We analyzed limb flares observed by the Hinode/EIS that observes extreme ultraviolet close to soft X-rays that can be observed the acceleration region. However, there is only one flare event that observed near the acceleration region, and which was already reported in other paper (Imada et al., 2013) . Therefore, we estimated the intensity of accelerated particles during solar flares statistically by using other flare radiation (white-light, hard X-ray, ultraviolet), and obtained the flare characteristics at the time of particle acceleration.
