A dimensionless parameter dependence study of intrinsic torque has been performed on a database of H- and I-mode plasmas from the Alcator C-Mod tokamak. The torque was determined by comparing intrinsic angular momentum density profiles just before and just after L–H and L–I transitions. The intrinsic torque has been found to scale as , with the parameter ranges 0.3 ⩽ β N ⩽ 1.5, 0.004 ⩽ ρ * ⩽ 0.011 and 0.04 ⩽ ν * ⩽ 0.9. Comparison with results from JET and DIII-D suggests that the intrinsic torque should be normalized by some measure of the device size. Depending upon this normalization, the estimated total intrinsic torques for ITER, SPARC and ARC are ∼20, ∼4 and ∼8 Nm, respectively.

C-Mod增强约束等离子体中固有转矩的无量纲参数缩放
已经对来自Alcator C-Mod托卡马克的H型和I型等离子体数据库进行了无量纲参数依赖性转矩的相关性研究。通过比较L–H和L–I过渡前后的固有角动量密度分布来确定扭矩。固有转矩已经发现规模为,与所述的参数范围0.3⩽ β Ñ ⩽1.5,0.004⩽ ρ * ⩽0.011和0.04⩽ ν * ⩽0.9。与JET和DIII-D的结果进行比较表明,应通过某种尺寸的设备尺寸对固有扭矩进行标准化。根据此归一化,ITER,SPARC和ARC的估计总内在转矩分别为〜20,〜4和〜8 Nm。
