High-z materials
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. WebHigh-Z materials are comprised of elements that have many electrons per atom. While high-Z materials are used to stop electrons and photons, they are also useful in stopping other charged particles to include assisting with protons. The second type of radiation is Galactic Cosmic Rays (GCRs).
