一种用于激光蒸发产生团簇束的高速脉冲气阀
A Double-solenoid Pulsed Valve Used for the Generationof Cluster Beams with Laser Vaporization Technique
摘要
报道一种双线圈弹簧结构脉冲气阀的成功研制。产生的气体脉冲宽度(FWHM)小于200 μs,在不加Skimmer时气体脉冲峰值强度为2×1022 molecules/sr·s。气阀的主要性能与国外用激光蒸发/分子束技术产生簇束的有代表性的实验室所用的同类气阀相比并不逊色。
Abstract
It is reported that a double-solenoid pulsed valve with pulse width less than 200 μs has operated successfully. The peak intensity of the produced gas pulse is about 2×1022 molecules/sr.s without Skimmer. The main features of the valve are comparable with those used in foreign representative laboratories for the generation of cluster beams with laser vaporization/molecular beam technique.
