The solid deuterium source of ultracold neutrons

摘要

The result of investigation can be used for new projects of solid deuterium sources at high flux reactors with heavy water reflectors. A heavy water is a good shield from high energy neutrons and gamma rays. That allows to have a low level of heat load at high flux of thermal neutrons (reactor P1K, Gatchina, reactor ILL, Grenoble). Another possibility is to use the solid deuterium sources at neutron spallation sources, where the relation of heat load to neutron flux is better than one for reactors.
