当涂敷于玻壳内壁上的光电阴极各处受到强光照射而产生光电发射时
发射层表面的电场将会使发射层晶体解体
并使正离子沿电场方向迁移
从而导致光电疲乏。本文讨论了层面场与光电疲乏的关系
给出了一种计算光电阴极正离子迁移的数学模型。这个模型能较好地说明若干实验中出现的物理现象。
昗hen the intensive light is incident uniformly upon the photocathode deposited on the inner wall of the bulb
the electricfield distribution of the emitter surface will make the crystals electrolytically dissociated and force the positive ions to move along the direction of the field that results in a photo-fatigue.This paper discusses the relation between the electric-field of the layer surface and the fatigue
and presents a calculating model of positive ion displacement of photocathode
which makes some practical phenomena interpretable in the experiments.
