摘要
对条纹相机所使用的一种具有双板电极结构的变像管(Bilamellar)进行了研究, 这种变像管使用平板状电极和电四极透镜等设计,改善了传统轴对称结构变像管存在的不足。通过仿真模拟的方法建立了Bilamellar变像管的工作模型, 对其结构构成、工作模式、成像特点等性能作出了分析评估。计算结果表明:根据这一思想设计的变像管结构可以更有效地控制空间电荷效应,并提高时间、空间分辨能力。
Abstract
A bilamellar image converter tube was introduced, which adopts plate poles and electric quadrupole lenses. Based on the bilamellar tube model, the structure, operation mode and imaging characteristics, etc. of the tube were analyzed. The results show that the bilamellar structure can effectively control the space-charge effect and thus increase the temporal/spatial resolution of imaging.
