Abstract
A new code has been developed and benchmarked with data from lower hyb rid current drive (LHCD) experiments in JET. The model includes stocha stic radial diffusion of electrons and scattering of lower hybrid (LH) waves. The code is validated by comparing calculated and experimental current drive efficiencies as well as calculated and measured hard X ray bremsstrahlung emission radial profiles. Reasonable agreement has been found for full LH current driven cases and LH plus moderate DC el ectric field.
