PbWO4 and CeF3 which are newly developed inorganic scinti1latr in our country have been studied. Photo-electricity detector systemes which have high γ sensitivity and relative insensitive to neutron and fast time response were assembled by using CeF3 and photomultiplier tube. The ratio of signal-to-noise for γ ray detection can be up to more than 10 times in close distance n,γ commix pulse radiation field by using this detector system.

对PbWO4和CeF3等近年国内新研制的无机闪烁体进行了系列研究，使用CeF3分别配光电倍增管和光电管，组合出了对γ辐射灵敏度高，对中子相对不灵敏，同时脉冲响应也快的光电探测系统，应用以此为基础的探测技术在近距离n，γ混合脉冲辐射场中，可将脉冲γ辐射探测信噪比提高一个量级以上。

The only difference between these two cells was that in Lenard's cell the electrons were taken from the cathode by light, whereas on the "3-electrode lamp" the cathode is a white-hot filament capable of sending into the vacuum currents of much higher intensity.

在研究过程中，莱纳德还发明了一种光电管，以加速电子和测量它们的能量，这种光电管是三极管最初的雏形，不同之处在于，在莱纳德的光电管中，电子是由阴极光发射的，而三极管中的阴极是白炽丝，可以向真空发射更高强度的电流。
