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…
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…
Testing CPT Invariance by High-Precision Comparisons of Fundamental Properties of Protons and Antiprotons at BASE
E. J. Wursten, M. J. Borchert, J. A. Devlin +24
The BASE collaboration at the Antiproton Decelerator facility of CERN compares the fundamental properties of protons and antiprotons using advanced Penning-trap systems. In previou…
Sympathetic cooling schemes for separately trapped ions coupled via image currents
C. Will, M. Bohman, T. Driscoll +18
Cooling of particles to mK-temperatures is essential for a variety of experiments with trapped charged particles. However, many species of interest lack suitable electronic transit…
