Sensitivity of equilibrium profile reconstruction to motional Stark effect measurements

S.H. Batha, F.M. Levinton, S.P. Hirshman, M.G. Bell, R.M. Wieland1996年被引用 8Nuclear FusionIF 3出版社

The magnetic-field pitch-angle profile, gamma p(R) identical to tan-1(Bpol/Btor), is measured on TFTR using a motional Stark effect (MSE) polarimeter. Measured pitch angle profiles, along with kinetic profiles and external magnetic measurements, are used to compute a self-consistent equilibrium using the free-boundary variational moments equilibrium code VMEC. Uncertainties in the q profile due to uncertainties in gamma P(R), magnetic measurements and kinetic measurements are found to be small. Subsequent uncertainties in the VMEC-calculated current density and shear profiles are also small

磁場のピッチ角分布、γ_p(R) ≡ tan^{-1}(B_pol/B_tor) は、モーションル・スターク効果(MSE)偏光計を用いてTFTRで測定された。測定されたピッチ角分布は、運動分布および外部磁気測定とともに、自由境界変分モーメント平衡コードVMECを用いて自己無撞着な平衡を計算するために使用される。γ_p(R)、磁気測定、および運動測定の不確かさに起因するq分布の不確かさは小さいことがわかった。VMECで計算された電流密度およびシア分布におけるその後の不確かさもまた小さい。
