An inexpensive and fast method for infiltration coating of complex geometry matrices for ISOL production target applications

摘要

An inexpensive, fast, and close to universal infiltration coating technique has been developed for fabricating fast diffusion-release ISOL targets. Targets are fabricated by deposition of finely divided (～1 μm) compound materials in a paint-slurry onto highly permeable, complex structure reticulated-vitreous-carbon-foam (RVCF) matrices, followed by thermal heat treatment. In this article, we describe the coating method and present information on the physical integrity, uniformity of deposition, and matrix adherence of SiC, HfC and UC_2 targets, destined for on-line use as targets at the Holifield Radioactive Ion Beam Facility (HRIBF).
