Titanium Gettering in Doublet III

摘要

The application of mild titanium gettering in the Doublet III tokamak has led to a significant improvement in the obtainable operating regimes and discharge parameters for all of the many plasma cross-sectional shapes studied. With gettering, low-Z impurities and radiated power are greatly reduced. The maximum line averaged electron density has increased 50% (anti n/sub e max/ approx. 1 x 10 exp 20 /m exp 3 ), corresponding to a Murakami coefficient of nearly 6. (ERA citation 06:009979)
