Sympathetic Cooling of Ions using Laser-Cooled One-Component Plasmas — •Michael Bussmann1, Ulrich Schramm2, Peter Thirolf1, Veli Kolhinen1, Jerzy Szerypo1, Juergen Neumayr1, Michael Sewtz1, and Dietrich Habs1 — 1Ludwig-Maximilians-Universitaet Muenchen, Am Coulombwall 1, 85748 Garching — 2Forschungszentrum Dresden-Rossendorf, Bautzner Landstraße 128, 01328 Dresden
We present new simulation results on sympathetic cooling of ions for precision experiments.
Using a laser-cooled one-component plasma of 105 24Mg+ ions it is possible to stop and sympathetically cool ions to mK temperatures. With the proposed cooling scheme fast and efficient cooling of rare nuclei for precision in-trap physics, e.g. subsequent mass measurements in Penning traps, becomes possible.
In the talk we will give an overview of previous results before presenting new results on the stopping dynamics, especially the interplay of collective dynamics, plasma stability and recooling efficiency.
