一种测量高压气体中离子漂移速度的方法

摘要

A method for measuring the drift velocity of ions in high pressure gas was proposed by using a pulsed X-ray generator as an ions producer and a high frequency digital oscilloscope as a recorder of the voltage signal on the load resistor. By this means, the drift velocity of xenon ions in 1. 5 MPa xenon gas was measured. The method is proved to be effective and simple for the drift velocity measurement of ions in high pressure gas.%利用脉冲X射线机作为离子触发源,用高频数字示波器记录负载电阻上的电压信号,通过曲线拟合得出离子在高压气体中的漂移速度.用该方法实测氙离子在1.5 MPa氙气中的漂移速度,结果表明,该方法可简便有效地测量高压气体中的离子漂移速度.
