摘要
对9个相同的闪烁探测器进行了硅凝胶灌封实验,所采用的GN-512型有机硅凝胶分为M和N组分,灌封配比为M∶N=1∶3。并将灌封前后探测器的输出进行了对比,给出了硅凝胶灌封对于该探测器输出信号影响的结果并从光收集的角度作了分析。试验表明,对该种结构的闪烁探测器,硅凝胶灌封后将使探测器的输出幅度普遍降低,最大可达70%左右。
For some special applications, it is necessary to fill detectors with Gel-silica to improve the reliability and stability of detectors. Filling Experiments to 9 same scintillation detectors were carried out, and the output amplitudes of these detectors, before and after they were filled with Gel-silica, were compared under the same conditions （including temperature, humidity, etc. ）. The organic Gel-silica, type of GN-512, was divided into two independent components, M and N. And the mixture of M and N, in the ratio 1：3, was used in this experiment. The results of the comparison were presented and analyzed in a sense of light collection in this paper. Experiments indicated that, for scintillation detectors which have the structure shown in figure 1, the output amplitudes of these detectors all reduced after they were filled with Gel-silica, even by 70%.
