报道一种场电离检测的Ｃｓ原子共振滤波方案。理论预计：原子系统的固有线宽约为６０ＭＨｚ，响应时间为１ｎｓ，量子效率为９９％；初步实验测得（包括实验系统因素）响应时间为１２０ｎｓ，最小可探测光强为１０ｎＪ。
A Cs ion resonance filter scheme for field ionization detection is reported. The theory predicts that the inherent bandwidth of the atomic system is about 60MHz, the response time is 1ns, and the quantum efficiency is 99%. The initial experimental results (including experimental system) show that the response time is 120ns and the minimum detectable light intensity is 10nJ.
