摘要：

The stability of ion motion in the Paul trap driven by rectangular waveforms was investigated. The stability region was determined by solving the equation of motion for an ion with fourth order Runge-Kutta method. The variation of stability region with the duty cycle was analyzed. The results showed the ability of mass analysis by changing the duty cycle without changing rf voltage. Also, a simple method of mass selection using rectangular waveforms was suggested.
