CER researchers awarded a grant to coordinate divertor materials experiments at the DIII-D tokamak facility

10 January 2007

Drs. Moyer and Rudakov received a renewal award of $60,906 from General Atomics for a period of 1 year for Dr. Rudakov to continue as the Divertor Material Exposure System (DiMES) Experimental Coordinator at the DIII-D National Fusion Facility, located at General Atomics. In this capacity, Dr. Rudakov is responsible for the planning, execution, analysis and publication of experimental results on the interaction of the tokamak boundary plasma with divertor and first wall materials using the sample exposure systems in the divertor (DIMES) and on the outer mid-plane (MiMES) of the DIII-D tokamak. To conduct this research, Dr. Rudakov coordinates the efforts of an international collaboration on plasma-wall interactions in fusion devices. He is using the sample exposure systems to explore several important issues for ITER and other burning plasma devices, including the net erosion of plasma-facing components, co-deposition of hydrogen (tritium) in thin films in tokamaks, and the lifetime of diagnostic mirrors in next-step tokamaks such as ITER.
