Title:
MODERATOR FOR MODERATING NEUTRONS
Document Type and Number:
WIPO Patent Application WO/2019/034043
Kind Code:
A1
Abstract:
Disclosed is a moderator for moderating neutrons, comprising a substrate (402) and a surface treatment layer (401) or a dry inert gas layer or a vacuum layer coated on the surface of the substrate (402), wherein the substrate (402) is prepared from a moderating material through a powder sintering process by using a powder sintering device so as to change powders or powder compacts into blocks, and the moderating material comprises 40%-100% parts by weight of aluminium fluoride; the surface treatment layer (401) is a hydrophobic material; and the surface treatment layer (401) or the dry inert gas layer or vacuum layer is used for isolating the substrate (402) from the water in the environment where the substrate (402) is located. The surface treated moderator can avoid the hygroscopic deliquescence of the moderating material during use, improve the quality of the neutron source and prolong the service life thereof.
