A time-of-flight coincidence detector is demonstrated. This detector is optimized for use in a pseudocontinuous resonance enhanced multiphoton ionization scheme that requires photoelectrons and photoions to be detected in coincidence. The detector utilizes two simultaneously operating charged particle detectors, one for the detection of electrons and the other for the detection of ions. In order to allow for field reversal, the detectors are physically identical, differing only by the value of applied voltages. Particular attention is given to the implementation of a charge-to-voltage transducer that allows for subnanosecond detection of both electrons and ions.
演示了一种飞行时间符合探测器。该探测器针对伪连续共振增强多光子电离方案进行了优化,该方案要求同时探测光电子和光离子。该探测器利用两个同时工作的带电粒子探测器,一个用于探测电子,另一个用于探测离子。为了实现场反转,这两个探测器在物理上是相同的,只是所施加电压的值不同。特别关注了电荷 - 电压传感器的实现,它能够对电子和离子进行亚纳秒级的探测。
