Abstract
In a radiation detector, an output extraction portion includes a first resistor chain, a first light detection portion of each of a plurality of radiation detection units being connected to the first resistor chain, and a second resistor chain, a second light detection portion of each of the plurality of radiation detection units being connected to the second resistor chain.
Claims7
A radiation detector comprising:
- a plurality of radiation detection units configured to detect scintillation light;
- and
- an output extraction portion electrically connected to the plurality of radiation detection units,
- wherein each of the plurality of radiation detection units includes
- a first scintillator portion having a first segment,
- a second scintillator portion having a second segment,
- a first light detection portion optically coupled to a first end surface of the first scintillator portion on one side in a predetermined direction, and
- a second light detection portion optically coupled to a second end surface of the second scintillator portion on the one side in the predetermined direction,
- the first scintillator portion and the second scintillator portion are optically coupled to each other in a region on the other side in the predetermined direction, and
- the output extraction portion includes
- a first resistor chain, the first light detection portion of each of the plurality of radiation detection units being connected to the first resistor chain,
- a second resistor chain, the second light detection portion of each of the plurality of radiation detection units being connected to the second resistor chain, and
- the first resistor chain and the second resistor chain are electrically independent from each other.
