摘要
叙述了脉冲式分子束阀及脉冲式分子束阀控制器的研制。控制器提供内/外触发选择,触发延时0.05~3.0ms(8档可选),开阀时间0.1~1.5ms(8档可选),开阀脉冲控制0.05~1.0ms(8档可选),关阀及反冲控制0.1~1.0ms(连续可调),并有同步脉冲输出和驱动电流监测。本装置产生的脉冲分子束流可满足同步幅射实验室的需要,控制器还可用于其它气阀的控制。
Pulsed Molecular Beam Valve and Its Controller//Xu Xilin, Yao Chuanrong (National Synchrotron Radiation Laboratory, University of Science and Technology of China, Hefei, 230026)
This paper describes the operation principle of a pulsed molecular beam valve and the design of its controller. The controller provides internal and external trigger selection: Trigger delay is 0. 05~3.0ms (8 steps), valve open time duration 0.1-1. 5ms(8 steps),valve open pulse control 0. 05-1. 0ms(8 step),valve close and bounce interval control 0.1-1.0ms (continuously adjustable). Synchronous pulse output and driving coil current monitoring are provided. The pulsed molecular beam produced by this apparatus can meet the requirements of synchrotron radiation laboratory. The controller can also be used for controlling other gas valves.
