photocathode

基本解释

With good light collection, about 30 % of the luminescence quanta may reach the photocathode.
在良好的光收集条件下，约30%的荧光量子可以到达光阴极。
At present, the cesium source used for manufacture of photocathode belongs to a neutral source which shows some advantages.
在光电阴极制备及对其作表面分析时，铯离子源较中性铯源有一定的优点。
It is very difficult to measure precisely the surface temperature of a photocathode in a vacuum system during the thermal cleaning.
然而，在热清洗过程中对处在真空系统中的光电阴极表面温度进行精确测量却是非常困难的。
