Aspects of ultracold neutron production in deuterium” Ultracold neutrons are neutrons with energies of about 100 neV, that can be stored in bottles with lifetimes comparable to the free neutron lifetime (~ 15 min). The fact that one can store UCN for such long periods makes them an excellent tool to study fundamental properties of the neutron; for example the neutron lifetime and electric dipole moment (EDM). The accuracy of such experiments with the present UCN sources is limited by statistics. Next generation experiments, that aim to improve these sensitivities, depend on the development of higher intensity UCN sources. One of the ways to increase the UCN intensity is to use an appropriate material as UCN converter; i.e. a medium that converts cold neutrons into UCN. |
