WebDec 17, 2015 · Dedicated DIII-D experiments coupled with modeling reveal that the net erosion rate of high-Z materials, i.e. Mo and W, is strongly affected by carbon concentration in the plasma and the magnetic pre-sheath properties. Different methods such as electrical biasing and local gas injection have been investigated to control high-Z material erosion. WebWith high Z materials, the bremsstrahlung (secondary radiation – X-rays) is associated. This radiation is created during the slowing down of beta particles while they travel in a very …
