Fluorescence calorimetry of an ion crystal
Marvin Gajewski, Wenbing Li, Sebastian Wolf +5
Motivated by the challenge of identifying intruder ions in a cold ion crystal, we investigate calorimetry from emitted fluorescence light. Under continuous Doppler cooling, the ion…
Robust Polarization Gradient Cooling of Trapped Ions
Wenbing Li, Sebastian Wolf, Lukas Klein +3
We implement three-dimensional polarization gradient cooling of trapped ions. Counter-propagating laser beams near nm impinge in linlin configuration, at a freque…
Efficient and robust photo-ionization loading of beryllium ions
Sebastian Wolf, Dominik Studer, Klaus Wendt +1
We demonstrate the efficient generation of Be ions with a 60 ns and 150 nJ laser pulse near 235 nm for two-step photo-ionization, proven by subsequent counting the number of io…
Microscopy with a Deterministic Single Ion Source
Georg Jacob, Karin Groot-Berning, Sebastian Wolf +6
We realize a single particle microscope by using deterministically extracted laser cooled Ca ions from a Paul trap as probe particles for transmission imaging. We demons…
Single particle microscopy with nanometer resolution
Georg Jacob, Karin Groot-Berning, Sebastian Wolf +5
We experimentally demonstrate nanoscopic transmission microscopy relying on a deterministic single particle source. This increases the signal-to-noise ratio with respect to convent…
Cooling antihydrogen ions for the free-fall experiment GBAR
Laurent Hilico, Jean-Philippe Karr, Albane Douillet +3
We discuss an experimental approach allowing to prepare antihydrogen atoms for the GBAR experiment. We study the feasibility of all necessary experimental steps: The capture of inc…
