    摘要: A cryogenic refrigerator includes a first refrigerant tube and a second refrigerant tube each comprising two tubes that are arranged on a cooling stage substantially parallel to each other and communicate with each other through a gas passage formed in the cooling stage. Phase differences are provided to oscillating gas pressures in the first and second refrigerant tubes, to cancel vibration of the cooling stage. Thus, the cryogenic refrigerator can be provided which can effectively reduce the vibration of the cooling stage caused by the oscillating gas pressure and can reduce the size thereof.

    摘要: A medium area (S) filled with liquid xenon (2) is formed between an external cylindrical body (1a) and internal cylindrical body (1b), and a pair of anode pads (11, 12) 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 (10) is disposed between a pair of anode pads (11, 12), and a plurality of photomultiplier tubes (5) is installed in two-dimensional form in the external cylindrical body (1a). Then, the gamma-ray reaction point within the liquid area (S) is identified from signals output from the anode pads (11, 12) and photomultiplier tubes (5).
