Orders of Magnitude Improved Cyclotron-Mode Cooling for Non-Destructive Spin Quantum Transition Spectroscopy with Single Trapped Antiprotons
B. M. Latacz, M. Fleck, J. I. Jaeger +21
We demonstrate efficient sub-thermal cooling of the modified cyclotron mode of a single trapped antiproton and reach particle temperatures below mK in p…
A 16 Parts per Trillion Comparison of the Antiproton-to-Proton q/m Ratios
M. J. Borchert, J. A. Devlin, S. E. Erlewein +20
The Standard Model (SM) of particle physics is both incredibly successful and glaringly incomplete. Among the questions left open is the striking imbalance of matter and antimatter…
Penning-Trap Mass Measurement of Helium-4
Sangeetha Sasidharan, Olesia Bezrodnova, Sascha Rau +3
Light-Ion Trap (LIONTRAP), a high-precision Penning-trap mass spectrometer, was used to determine the atomic mass of He. Here, we report a 12 parts-per-trillion measurement o…
Image-current mediated sympathetic laser cooling of a single proton in a Penning trap down to 170 mK axial temperature
C. Will, M. Wiesinger, P. Micke +22
We demonstrate a new temperature record for image-current mediated sympathetic cooling of a single proton in a cryogenic Penning trap by laser-cooled Be. An axial mode temp…
Trap-integrated fluorescence detection based on silicon photomultipliers in a cryogenic Penning trap
Markus Wiesinger, Florian Stuhlmann, Matthew A. Bohman +21
We present a fluorescence-detection system for laser-cooled 9Be+ ions based on silicon photomultipliers (SiPM) operated at 4 K and integrated into our cryogenic 1.9 T multi-Penning…
The electron mass from -factor measurements on hydrogen-like carbon C
Florian Köhler, Sven Sturm, Anke Kracke +3
The electron mass in atomic mass units has been determined with a relative uncertainty of , which represents a 13-fold improvement of the 2010 CODATA value. The…
