Abstract

The NF09 topical group was charged with soliciting input to Snowmass on the topic of artificial neutrino sources. In this report, we attempt to catalogue all new or upgraded artificial neutrino sources that are being considered by the global neutrino physics community over the next decade. This report also highlights projects that can improve our knowledge of the fluxes from these sources, which is important to maximize their use.
