Abstract
A semiconductor detector includes a plate-shaped semiconductor part, a signal output electrode for outputting a signal provided at one surface of the semiconductor part, a plurality of curved electrodes provided at the one surface of the semiconductor part and which have distances from the signal output electrode that are different from each other, and an arc-shaped collection electrode for collecting an electric charge generated at the semiconductor part. The plurality of curved electrodes are applied with voltage to generate in the semiconductor part a potential gradient in which a potential varies toward the signal output electrode. The collection electrode is located at a part of the semiconductor part between an adjacent pair of curved electrodes. The collection electrode is connected to a curved electrode located a distance from the signal output electrode shorter than a distance between the collection electrode and the signal output electrode among the curved electrodes.
