Drs. Albert Young & Kent Leung along with collaborators from the European Spallation Source (Lund, Sweden), Los Alamos National Lab, and Oak Ridge National Lab have published a paper describing their concept of how to produce a next-generation ultracold neutron source. Such a source can be used to dramatically improve ultracold neutron experiments or allow whole new type of experiments that address questions in nuclear and particle physics, cosmology, astrophysics and condensed matter physics.
The paper was featured as a Editor’s pick in the Journal of Applied Physics (https://aip.scitation.org/doi/10.1063/1.5109879). A Scilight article that was published along with it can be found here: https://aip.scitation.org/doi/10.1063/10.0000359
