We have been developing silicon foil X-ray mirrors using a hot plastic deformation process for future space observations that require high angular resolution and a large effective area. Thanks to the high rigidity and excellent reflective surface quality of silicon, these mirrors may offer both reduced weight and improved angular resolution compared to conventional foil optics. In this study, we optimized the processing conditions and irradiated a champion sample with X-rays, achieving roughly twice the performance of our conventional sample.
