Abstract

Zero current density was observed within measurement errors in the core (r/a≤0.2) of JET OS plasmas with a LHCD prelude. The magnetic field pitch angle in the plasma was measured by the motional stark effect (MSE) technique. It was found that the overall measurement error is typically ±0.2°-0.3° when calibration uncertainties are included.
