摘要

描述了一种记录碱金属和碱土金属卤化物超热气体动力种子分子束飞行时间光谱的方法。这种方法无需考虑硬件时间延迟来确定和调整光谱。该方法基于两个二次电子倍增器对离子的记录，离子是在具有离子键的分子的碰撞诱导解离（CID）过程中形成的，这两个二次电子倍增器沿光束通道与光束斩波器保持不同的距离。

Time-of-Flight Spectroscopy of Hyperthermal Molecular Beams of Alkali and Alkaline Earth Metal Halides

A method for recording time-of-flight spectra of hyperthermal gas-dynamic seeded molecular beams of alkali and alkaline earth metal halides is described. This method is free of the need to determine and adjust spectra taking hardware time delays into account. The method is based on registering ions, which are formed in the collision-induced dissociation (CID) of molecules with ionic bonds, by two secondary-electron multipliers located at different distances from the beam chopper along the beam passage.
