Parametric instability influence on isotope separation by ion-cyclotron resonance method

Abstract

Solution of the dispersion equation for linear potential ion cyclotron oscillations with characteristic parameters used for selective ion cyclotron resonance separation of gadolinium isotopes has revealed the presence of the shortwavelength unstable oscillation in the ion cyclotron frequency range. Computer simulation of this instability by means of macro particle technique has shown that this instability may be responsible for turbulent heating of both resonant and nonresonant ions obtaining large transversal energy. It can decrease the efficiency of this method.
