We demonstrate efficient sub-thermal cooling of the modified cyclotron mode of a single trapped antiproton and reach particle temperatures $T_+=E_+/k_\text{B}$ below $200\,$mK in preparation times shorter than $500\,$s. This corresponds to the fastes

Autor: Latacz, B. M., Arndt, B. P., Devlin, J. A., Erlewein, S. R., Fleck, M., Jäger, J. I., Micke, P., Umbrazunas, G., Wursten, E., Abbass, F., Schweitzer, D., Wiesinger, M., Will, C., Yildiz, H., Blaum, K., Matsuda, Y., Mooser, A., Ospelkaus, C., Smorra, C., Sótér, A., Quint, W., Walz, J., Yamazaki, Y., Ulmer, S.

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 at a leak rate < $1\times 10^{-9}$ mbar$\cdot$ l/s. Its thickness of ap

The BASE collaboration at the antiproton decelerator/ELENA facility of CERN compares the fundamental properties of protons and antiprotons with ultra-high precision. Using advanced Penning trap systems, we have measured the proton and antiproton magn
