Development of secondary sources of very cold and ultra cold neutrons for the European Spallation Source as part of the HighNESS project

Investigation of different options of sources of very cold and ultra cold neutrons for the European Spallation Source. This includes development of simulations to assess the potential of novel moderator materials called clathrate hydrates and novel neutron reflectors made of magnesium hydrate. Both fundamental physics neutron scattering can benefit from even slower spectrum of neutrons.
