Design of a Surface Trap for Freely Rotating Ion Ring Crystals

Po-Jen Wang, Tongcang Li, Crystal Noel +2

We present a design of an r.f. trap using planar electrodes with the goal to trap on the order of 100 ions in a small ring structure of diameters ranging between 100 μm and 200 $…

Resistive and sympathetic cooling of highly-charged-ion clouds in a Penning trap

M. Vogel, H. Häffner, K. Hermanspahn +3

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…
