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…
High-precision measurement of the proton's atomic mass
Fabian Heiße, Florian Köhler-Langes, Sascha Rau +9
We report on the precise measurement of the atomic mass of a single proton with a purpose-built Penning-trap system. With a precision of 32 parts-per-trillion our result not only i…
Resolution of Single Spin-Flips of a Single Proton
A. Mooser, H. Kracke, K. Blaum +7
The spin magnetic moment of a single proton in a cryogenic Penning trap was coupled to the particle's axial motion with a superimposed magnetic bottle. Jumps in the oscillation fre…
Observation of Spin Flips with a Single Trapped Proton
S. Ulmer, C. C. Rodegheri, K. Blaum +4
Radio-frequency induced spin transitions of one individual proton are observed for the first time. The spin quantum jumps are detected via the continuous Stern-Gerlach effect, whic…
