用于PET信号探测的PIN的设计与研制

Design and Manufacture of PIN Photodiode Used in PET

根据PIN用于实现PET光子探测的可行性分析及探测过程对PIN管的要求 ,在理论分析的基础上 ,优化设计了工作于 480nm入射光波长的PIN光电二极管的结构参数、材料参数以及工艺参数 ,研制的样管达到了可行性分析的指标要求 ,而且PIN管作为光子探测器件具有结构简单 。

Base on the feasible analyse and the preferences of PIN photodiode used in PET photon detector, by choosing proper configuration, material and technology parameters, the performance of PIN photodiode illuminated by 480 nm incident light is improved. The results show that,the pattern diodes achieve the purpose of feasible analyse. Used in photon detector PIN photodiode have simple configuration and better ratio of performance to price.
