摘要：

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, T(i), and ion thermal diffusivity, chi(i), are derived under steady-state conditions. The inferred chi(i), for 0.3 < rho = r/a < 0.5, is in the range 0.5-2.5 m2 s-1. The ion thermal diffusivity is higher than, and its scaling with plasma current opposite to, that predicted by neoclassical theory.
