Moderator material, useful for energy reduction of cold or thermal neutrons to a low energy, comprises hydrogen, and a barrier surrounding the hydrogen, where the barrier is a matrix material having closed pores, which enclose hydrogen gas

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a moderator material designed to slow down (moderate) cold or thermal neutrons to even lower energy levels. The moderator consists of hydrogen gas trapped within closed pores of a surrounding matrix, with the pores being micro- or nanometer in size. The hydrogen is primarily in the form of molecular ortho-hydrogen and para-hydrogen, which helps in efficient neutron moderation.
