Sympathetic cooling of charged particles in Penning traps using electron cyclotron radiation
Jost Herkenhoff, Jonathan Notter, Klaus Blaum
We present a new technique for cooling arbitrary charged particles in a Penning trap by utilizing self-cooled electrons stored in a separate, macroscopically distant Penning trap a…

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…
