Deuterium Cryostat Plugs For Neutron Application
A structure was designed for NIST to hold a cryostat assembly. The structure, known as a cryostat plug, serves as a support for the cryostat support as well as a radiation shield. The plug was built to house the new liquid deuterium cold neutron source that replaced the former liquid hydrogen source and its plug assembly. The cryostat plug is a large stainless steel welded structure that is made up of two separate weldments, a top and bottom weldment, and two side pieces to connect them.
