Original Abstract Submitted
A radiation detector obtained by arranging a plurality of pixels on a semiconductor substrate configured to convert incident radiation into charges is provided. The plurality of pixels comprise a first pixel arranged along an outer edge of the semiconductor substrate and a second pixel arranged closer to a center of the semiconductor substrate than the first pixel. The first pixel comprises a plurality of first electrodes on a principal surface of the semiconductor substrate, the second pixel comprises a second electrode on the principal surface, and an area of the second electrode is larger than an area of each of the plurality of first electrodes. A plurality of capacitors configured to accumulate signals generated by the plurality of pixels are further comprised so that one capacitor is connected in correspondence with each of the plurality of first electrodes and the second electrode.
