Precision spectroscopy on Be overcomes limitations from nuclear structure

Stefan Dickopf, Bastian Sikora, Annabelle Kaiser +7

Many powerful tests of the Standard Model of particle physics and searches for new physics with precision atomic spectroscopy are plagued by our lack of knowledge of nuclear proper…

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…

Ultra thin polymer foil cryogenic window for antiproton deceleration and storage

B. M. Latacz, B. P. Arndt, J. A. Devlin +21

We present the design and characterisation of a cryogenic window based on an ultra-thin aluminised PET foil at T < 10K, which can withstand a pressure difference larger than 1bar a…

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…

BASE-STEP: A transportable antiproton reservoir for fundamental interaction studies

C. Smorra, F. Abbass, M. Bohman +26

Currently, the only worldwide source of low-energy antiprotons is the AD/ELENA facility located at CERN. To date, all precision measurements on single antiprotons have been conduct…
