High magnification optical imaging systems for the characterization of soft X‐ray focii
Journal of Synchrotron Radiation, Volume 32, Issue 6, Page 1479-1490, November 2025.We developed compact soft X‐ray imaging systems optimized for ultra‐high‐vacuum environments, achieving micrometer‐level spatial resolution with high collection efficiency. Characterization confirmed excellent sensitivity and linearity, with applications demonstrated in caustic measurements and grating interferometry for wavefront analysis.We present a

A Si/CdTe Semiconductor Compton Camera [PDF]
, 2005 We are developing a Compton camera based on Si and CdTe semiconductor imaging devices with high energy resolution. In this paper, results from the most recent prototype are reported. The Compton camera consists of six stacked double-sided Si strip detectors and CdTe pixel detectors, which are read out with low noise analog ASICs, VA32TAs.
