Method for Measuring Drift Velocity of Ions in High Pressure Gas

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.
