Abstract

The stability of hexapole rf trap under DC electric field is theoretically investigated. Analytical arguments based on the 3D slow-fast Kapitsa method are developed to find the locus of the minimum in the effective potential. We investigate the motions with both vanishing and not vanishing angular momentum with respect to the z-axis. The numerical analysis confirms the theoretical results.
