介绍了一种用于飞行时间质谱仪的新型辉光放电离子源。该离子源在微秒级脉冲（瞬短脉冲）模式下工作。实验结果表明，瞬短脉冲辉光放电的电流比直流辉光放电有数量级的提高。对瞬短脉冲辉光放电离子源与质谱仪的接口的结构要求相当苛刻，必须用一块可加工陶瓷片屏蔽采样板，把采样板与辉光放电的阳极隔开，才能达到良好的真空及溅射。以黄铜为样品，瞬短脉冲辉光放电的瞬时溅射率达到24．4μg／s·mm2。就黄铜样品的典型谱图进行了讨论。
A new type of glow discharge ion source for time of flight mass spectrometer is introduced. The ion source operates in the microsecond pulse (momentary short pulse) mode. The experimental results show that the instantaneous short-pulse glow discharge current than the DC glow discharge an order of magnitude increase. The structure of the interface between the instantaneous short-pulse glow discharge ion source and the mass spectrometer is rather harsh. A piece of machinable ceramic sheet must be used to shield the sampling plate from the anode of the glow discharge to achieve a good vacuum and splash Shot. With brass as sample, the instantaneous short-pulse glow discharge instantaneous sputtering rate reached 24.4μg / s · mm2. A typical spectrum of brass samples is discussed.
