Producing and understanding ultracold neutrons for PanEDM, quantum sensing, and new applications
Prof. Dr. Skyler Degenkolb (Universität Heidelberg LEPP)

Ultracold neutrons (UCN) enable long observation times up to several hundred seconds, opening unique possibilities for precision measurements in low-energy particle physics. However, producing large quantities is challenging and most experiments throughout UCN physics have been statistically limited. Advances in producing UCN with low-temperature superfluid helium have recently led to long-duration storage experiments, with unprecedented UCN density, in the new instrument SuperSUN at the Institut Laue-Langevin in Grenoble.

I will describe the construction and operation of SuperSUN, the interpretation of measurements performed to date, and the challenges associated with transporting and studying UCN at extremely low energies. Prospects for physics measurements with the PanEDM experiment, and other highlighted applications, will also be presented.
