Background technology
The non-test surface of scintillator in scintillator detector must carry out lead shield process, normally uses certain thickness stereotype to shield outward at scintillator.
At present, a kind of shielding mode of scintillator is each non-test surface by using the identical stereotype 100 of thickness to be attached to scintillator 1, then twist screw 3 by metal shell 2 to fix, such scintillator shielding mode causes the junction between every two non-test surfaces to there is gap, see Fig. 1-4, in Fig. 2,4, beam 4 is there is between horizontal stereotype and vertical stereotype, obviously, this beam 4 just forms this gap, and this gap forms the beeline channel from scintillator to the external world.
Another kind of scintillator shielding mode is that scintillator non-spy side is when placing stereotype, the stereotype of scintillator corner is folded up, although doing the junction avoided between every two non-test surfaces is like this problem that there is gap, but cannot ensure that again the thickness of the stereotype of scintillator corner is identical with the thickness of the stereotype at plane place, such mode and front a kind of mode all can affect the performance of detector.
In addition, it is vertical relation that the screw mounting means using metal shell 2 to fix scintillator 1 is generally metallic screw 3 with test surface, as shown in Figure 5, it is possible that this metallic screw 3 mounting means needs to consider that metallic screw 3 can destroy that stereotype and scintillator directly contact, stereotype is just needed to evade metallic screw when mounted, a problem that may occur so is again that the stereotype thickness near metallic screw 3 is less than the stereotype thickness in other region, and this also can affect detector performance.
