电离检测的铯原子滤光器

Cs atomic resonance filter of ionization detection

报道了一种新型电离检测的原子滤光器。它是在封装的电子倍增器中配上一阴极电场极板，并充入适量铯金属制作而成。初步实验测得：最小可探测光强为１０ｎＪ，脉冲响应宽度小于５０ｎｓ。

This paper reported a new type Cs atomic resonance filter detected by ionization. The filter was fabricated by injecting an electrode and filling cesium in an electron amplifier. The previous experiment show that the lowest detectable energy is 10nJ,the time response is 50ns.
