Problem based on existing detector module array of packages existence, this utility model adopts the wedge shape installing plate that two detector cells left and right sides array packages are formed the detector encapsulation unit, by dowel hole adjacent detector module is accurately located then, make three to five detector encapsulation units array composition detector module vertically by bolt again.If one of them detector cells goes wrong, only need replacing problem detector encapsulation unit, the replacing quantity of detector cells is saved maintenance cost when having reduced maintenance.During the detector system upgrading, the detector encapsulation unit that only needs to increase respective numbers by the upgrading requirement gets final product.
This utility model also can be respectively equipped with some glue grooves in the left and right sides of wedge shape installing plate, and each glue groove is with respect to the crystal setting of detector cells.
Can to make things convenient for the fixing of detector cells and wedge shape installing plate, also be beneficial to unnecessary adhesive and discharge from the slit between the adjacent glue groove by adhesive on the point in the glue groove.
This utility model also can be respectively equipped with groove in the left and right sides of wedge shape installing plate, and described groove is with respect to the photomultiplier tube setting of detector cells.Be beneficial to dodge photomultiplier tube, can make tightr, the combination stably of detector cells and wedge shape installing plate.
In order more stably to connect, this utility model is provided with two dowel holes in the front side of wedge shape installing plate, is provided with two dowel holes at the rear side of wedge shape installing plate, each dowel hole be separately positioned on the wedge shape installing plate axially on.
Described installing hole is provided with two, be separately positioned on the wedge shape installing plate axially on.
In addition, be respectively equipped with the package casing installing hole at front side and the rear side of wedge shape installing plate, outside the detector encapsulation unit, be nested with shell, between shell and shell installing hole, connecting bolt is set.Package casing is assisted the function of fixed detector unit simultaneously to realize detector lucifuge, protection photomultiplier tube and associated electronics.
