从微通道板光电倍增模型着手,深入研究复合波导阳极的透射与位敏阳极对真空倍增系统造成的约束条件,并采用Mott插值方法研究了该新型光电器件电子光学特性。首先介绍了复合波导阳极结构与工作原理,给出了透射阳极与位敏阳极之间的对应关系,在此基础上分析了高速信号检测功能和入射光轴精确定位功能的约束关系,给出了相应的器件设计与实验方法,最后在真空炉中进行了该新型器件的验证性试验。试验结果表明了这种新型器件在理论和实践层面的可行性,但探索极间隧穿电压自适应调整机制将成为拓展其应用场合的必然趋势。

To start from microchannel-plate photoelectric multiple model, constraint conditions for vacuum multiplier system caused by anodized transmission of composite waveguide and position-sensitive anodes were studied deeply, and Mott interpolation method was employed to research the electro-optical properties of new optoelectronic device. Firstly, structure and working principle of composite waveguide anode were introduced, and the correspondence between the transmission anode and position-sensitive anode was given. On this basis, constrained relationship between high-speed signal detection and precise positioning of incident light axis was analyzed, and the corresponding devices design and experimental methods were given. Finally, the verification testing of the new device was conducted in vacuum furnace. Test results show that the new device is feasible both in theory and practice,to search for the adaptive adjustment mechanism of interelectrode tunneling voltage is a trend as inevitable for extending its application field.
