Abstract
We present an experimental method for stabilization of stored self-colliding ions at density 30 times greater than the space-charge limit (SCL) density. Previously, instabilities have prevented stable storage of ions in excess of the SCD density. Electrons were made to oscillate through the ions; the electron frequency was a critical stabilization parameter and varied by an open-loop (nonfeedback) application of an external field. The observations are compatible with a nonlinear stabilization effect not hitherto used in particle systems.Keywords
