A Cryogenic Penning Trap Based on Permanent Magnets
F. Völksen, K. K. Anjum, R. P. Czampiel +30
We report on a Penning trap based on NdFeB permanent magnets operated at 4\,K with a magnetic field strength of 280\,mT. Reliable loading and confinement of protons, H ions,…
Trapping of electrons and ions in a dual-frequency Paul trap
Vladimir Mikhailovskii, Natalija Sheth, Guofeng Qu +12
We demonstrate the operation of a dual-frequency Paul trap and characterize its performance by storing either electrons or calcium ions while applying two quadrupole fields simulta…
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…
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…
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…
