Title: Thermo-Mechanically Stable Tungsten Powders as Solid Catchers for the Fast Release of Stopped Rare Isotopes (Phase I Final Report)

Technical Report ·
OSTI ID:1579858

InnoSense LLC (ISL) explored the development of sinter-inhibited, refractory tungsten (W) powders for use as solid catchers at high temperature and extended periods. These solid catchers with thicknesses in the range of ~20 g/cm2 will complement gas catchers, which are the FRIB base-line concept for stopping energetic rare isotopes and delivering them for stopped-beam research or for reacceleration. The W powders when pressed into a loose compact are candidates for stopping light ions that require more stopping material than is feasible with helium gas currently used in gas catchers. This strategy shows substantial improvements as the open structures (i.e., minimal sintering) of the powders promotes fast effusion of stopped isotopes. Solid catchers using this technology can make for a very compact system that is compatible with location at the focal plane of the FRIB Fragment Separator to enable parasitic delivery of a second radioactive beam.
