Single Electrons in a Dual-Plane Printed-Circuit-Board Penning Trap
Zirui Fang, Benedict A. D. Sukra, Xing Fan
We demonstrate single-electron trapping and detection in a two-dimensionally scalable dual-plane printed-circuit-board Penning trap. We characterize deterministic electron loading,…

One-Positron Quantum Cyclotron
T. G. Myers, L. Soucy, B. A. D. Sukra +2
A one-positron quantum cyclotron is realized with a single positron suspended indefinitely in the magnetic field of a Penning trap. This opens the possibility of quantum measuremen…

One-Electron Quantum Cyclotron as a Milli-eV Dark-Photon Detector
Xing Fan, Gerald Gabrielse, Peter W. Graham +6
We propose using trapped electrons as high- resonators for detecting meV dark photon dark matter. When the rest energy of the dark photon matches the energy splitting of the two…
