Resistive and sympathetic cooling of highly-charged-ion clouds in a Penning trap
arXiv:1410.8656 · doi:10.1103/PhysRevA.90.043412
Abstract
We present measurements of resistive and sympathetic cooling of ion clouds confined in a Penning trap. For resistive cooling of a cloud consisting of one ion species, we observe a significant deviation from exponential cooling behavior which is explained by an energy-transfer model. The observed sympathetic cooling of simultaneously confined ion species shows a quadratic dependence on the ion charge state and is hence in agreement with expectations from the physics of dilute non-neutral plasmas.
