Study of a cylindrical ion trap supplied by a periodic impulsional potential

Authors


Abstract

This article reports on some theoretical studies concerning the impulsional mode of a cylindrical ion trap (CIT) supplied with a periodic impulsional radio frequency (rf) voltage of the form VaccosΩt/(1 − kcost) with 0 ≤ k < 1. The performance characteristics of CIT impulsional mode, for the twelve stability regions, were computed using fifth order Runge-Kutta method and were compared to the classical sinusoidal mode k = 0. Also, the results show that, for the same equivalent operating point in two stability diagrams (having the same βz) the associated modulated secular ion frequencies behavior are the same.
