Experimental setup for quantum logic inspired cooling and detection of single (anti-)protons — •Johannes Mielke1, Teresa Meiners1, Malte Niemann1, Anna-Greta Paschke1,2, Matthias Borchert3,1, Amado Bautista-Salvador2,1, Juan Manuel Cornejo1, Stefan Ulmer3, and Christian Ospelkaus1,2 — 1Institut für Quantenoptik, Leibniz Universität Hannover — 2Physikalisch Technische Bundesanstalt, Braunschweig — 3Ulmer Initiative Research Unit, RIKEN
We present concepts for cooling and manipulation of an (anti-)proton in a Penning trap using a co-trapped laser-cooled atomic ion, inspired by the proposal by Heinzen and Wineland [1]. Within the BASE collaboration [2], these techniques could be applied to g-factor based tests of CPT invariance with trapped (anti-)protons.
We discuss trap geometries, laser systems and imaging optics for loading, cooling, manipulation and detection of the trapped atomic ion and report on the current status of the experiment. We acknowledge funding by ERC StG “QLEDS” and DFG SFB DQ-mat and support by the BASE collaboration.
