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…
