title: Study of a cylindrical ion trap supplied by a periodic impulsional potential.
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 V(ac)cosΩt/(1-kcos2Ωt) 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 β(z)) the associated modulated secular ion frequencies behavior are the same.
