The pitch angle predicted by the transport analysis code TRANSP was compared with Motional Stark Effect (MSE) data. TRANSP was initialised in early rampup phase using a measured pitch angle profile but evolved the current profile using the magnetic field diffusion equation thereafter. The comparison was carried out on a wide range of pulses, including cases where a current hole was established in the preheating phase. Beyond confirming that a neoclassical model of the resistivity is superior to the classical one in modelling the evolution of the current profile in JET, the results indicate that the TRANSP prediction is nearly always within the 95% confidence band of the MSE data. In addition, it is shown that the TRANSP q-profile is consistent with MHD data and Faraday rotation polarimetry data.
