Abstract

A medium area (S) filled with liquid xenon () is formed between an external cylindrical body () and internal cylindrical body (), and a pair of anode pads () are disposed in two-dimensional form in opposite end portions of the medium area (S) in the intersection direction with respect to the gamma-ray incident direction. An intermediate electrode () is disposed between a pair of anode pads (), and a plurality of photomultiplier tubes () is installed in two-dimensional form in the external cylindrical body (). Then, the gamma-ray reaction point within the liquid area (S) is identified from signals output from the anode pads () and photomultiplier tubes ().
