stability of trapped ions in paul trap with rotating bias field

We investigated the motion and stability of ions in a radiofrequency trap with rotational bias field. Beginning with the extensively studied stability diagram for the Paul trap given by solutions to the Mathieu equation, we look for regions of instability created by the resonant electric field term. Additionally, we examine the effect of the bias field on laser-cooling in the trap. We also report on the design of an ion trap optimized for precision measurements of nuclear CP-violation in molecular ions.
