摘要：
The magnetic-field pitch-angle profile, gamma(p)(R) = tan(-1)(B-pol/B-tor), 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.
