Light Dark Matter Search with SOIPIX

We propose a light dark matter search experiment using an SOI pixel detector (SOIPIX). The event-driven SOIPIX can be a powerful tool for detecting light WIMPs because of its low energy threshold (< 1 keV) and high timing resolution (few {\mu}s). In this study, we evaluate the performance of an SOIPIX prototype detector and we examine the required specifications of SOIPIX for our target sensitivity.
