UCN storage in small cells for the (EDM)^n project
Experiments based on storage of ultracold neutrons (UCN) are strongly limited by the absolute densities that existing sources can deliver to experiments. ¿Superthermal¿ sources based on 4He achieve in-situ densities exceeding 100 UCN/cc, with higher values expected from new instruments, but the densities in experiments remain practically limited to a few UCN/cc. Present-generation experiments face intrinsic limitations due to volume dilution and lossy transport. The (EDM)^n project seeks to prepare new technological solutions for next-generation experiments, where higher densities are needed to reach new levels of statistical precision. A multi-cell in-situ experiment is envisioned, based on small modular cells that serve simultaneously as UCN source and EDM spectrometer. Recent studies pioneered by the SuperSUN-PanEDM collaboration have identified materials with promising storage properties for small cryogenic cells. This proposal seeks to further explore the most promising cell configurations in terms of UCN storage, obtaining baseline results to inform the preparation of future experimental campaigns.
