Shape reconstruction of steady state divertor plasma on QUEST

In the present RF-driven plasma with a lot of high-energy electrons, there may be anisotropic plasma pressure, which makes difficult a usual equilibrium analysis, but the CCS method can reconstruct the plasma shape precisely regardless of the anisotropy. And the plasma current effect in the open magnetic surfaces outside of the closed magnetic surfaces is considered in the RF-driven plasma. In the reconstruction process, SVD (Singular Value Decomposition) is used and optimal criterion function for GCV (Generalized Cross Validation) is estimated concerning truncation or reduction of the small-SV components.
