Title:     [Quantum&Precision Forum] Penning trapped electron for Dark Matter searches

Abstract: The toolkit of quantum technologies developed in atomic, molecular and optical physics are ideally suited to enhance the search for dark matter axions with masses above ~40 micro eV. I will present an overview of a new experimental effort under construction at Imperial College, developing technologies to detect DFSZ axions with masses above 120 micro eV. We plan to use a large mode area Fabry-Perot cavity to efficiently convert axions into microwave photons. Compared to other geometries, the Fabry-Perot cavity can present a large mode volume and high-quality factor and can be easily tuned. Once converted into microwaves, the radiation will be detected using an electron in a Penning trap as a single photon counter. Individual microwave absorption events will change the cyclotron state of the electron, causing measurable shifts in the trapped particle's oscillation frequencies. This versatile device will also open other possible detection routes for alternative dark matter candidates and cosmological phenomena.
