Ohmic ion temperature and thermal diffusivity profiles from the JET neutron emission profile monitorFunded under: FP2-FUSION 10C
The JET neutron emission profile monitor was used to study ohmically heated deuterium discharges. The radial profile of the neutron emissivity is deduced from the line integral data. The profiles of ion temperature and ion thermal diffusivity are derived under steady-state conditions. The inferred thermal diffusivity value is in the range 0.5 - 2.5 m2/s. The ion thermal diffusivity is higher than, and its scaling with plasma current opposite to, that predicted by neoclassical theory.
