Description
The electron in a Penning trap dark matter detection experiment is part of the Quantum Enhanced Particle Astrophysics (QuEPA) project at Imperial College London. The experiment aims to detect axion dark matter using a single electron confined in a cryogenic Penning trap. Microwave photons produced in the axion dark matter converter can be absorbed by the trapped electron, driving cyclotron transitions. These transitions induce a measurable phase shift in the electron’s axial motion, which is detected using a fast phase-sensitive measurement technique. This poster presents the motivation and advantages of using a single-photon quantum sensor for axion dark matter detection, along with the latest experimental results from the detection system.
