Description
Ultracold neutrons (UCN) enable precision measurements of fundamental neutron properties through their unique ability to be stored and manipulated at velocities below 5-7 m/s. At sufficient UCN densities, these measurements can probe beyond-standard-model (BSM) physics with sensitivity comparable to or exceeding high-energy collider experiments, while also enabling novel applications in surface science characterization.
Current UCN sources are limited by maximum allowable target irradiation currents, constraining achievable densities. We present a low-enriched uranium (LEU) fission plate design that enhances UCN production by a factor of 8-15 without increasing beam current. This approach leverages uranium’s high fission cross-section to amplify the primary neutron flux output from the UCN production target.
Our presentation will detail the design optimization, including: neutron transport modeling, thermal management solutions for elevated heat loads, fabrication methodology, operational lifetime projections, and integration with the existing UCN source design. The fission plate configuration provides an optimal neutron source while mitigating typical challenges associated with high-intensity neutron environments, paving the way for next-generation fundamental physics measurements.
