Abstract
Provided are a radiation detector and a radiation detection apparatus in which the efficiency of detecting radiation is enhanced by increasing a portion capable of detecting radiation. A radiation detector includes a semiconductor part having a plate-like shape, the semiconductor part being provided with a through hole penetrating the semiconductor part, one surface of the semiconductor part being an incident surface for radiation. The semiconductor part has a sensitive portion capable of detecting incident radiation, the sensitive portion including an inner edge of the incident surface.
Claims11
A radiation detector, comprising:
- a semiconductor part having an incident surface for radiation and a back surface;
- and
- the semiconductor part including a through hole penetrating from the incident surface to the back surface, wherein
- the semiconductor part has a sensitive portion capable of detecting incident radiation, and
- the sensitive portion includes an inner edge that is an edge of a peripheral portion of the through hole on the incident surface.
A radiation detector, comprising:
- a semiconductor part having an incident surface for radiation and a back surface;
- the semiconductor part including a through hole penetrating from the incident surface to the back surface;
- a first electrode continuously covering the incident surface up to an inner edge that is an edge of a peripheral portion of the through hole on the incident surface;
- and
- a plurality of second electrodes, provided on the back surface of the semiconductor part, for applying voltage to the semiconductor part between the plurality of second electrodes and the first electrode.
