Abstract
A nuclear detector, comprises a scintillation crystal array including a plurality of scintillation crystal bars of the same size arranged closely and in sequence, a light guide, and a photodetector array including a plurality of photodetectors arranged in sequence. The photodetectors have a cross-sectional area greater than that of the scintillation crystal bars, and the light guide includes a top surface coupled to the scintillation crystal array, an opposed bottom surface coupled to the photodetector array and a side surface. The light guide has a thickness in a range of 0.1 mm to 40 mm. The light guide further includes a slit adjacent to an edge of the light guide, and the slit is configured to extend from the top surface toward the bottom surface of the light guide and the slit has a depth in a range of 0.1 to 0.5 times the thickness of the light guide.
