Abstract
The particle transport of low density (∼1012 m-3) and low energy (<20eV) electrons is studied with a directed electron beam in the Tohoku University Heliac. The particle diffusion coefficient is estimated experimentally using the emissive filament technique. We investigate the coefficient's dependence on magnetic field strength, collision frequency and electron beam energy. The measured dependence is similar to the dependence calculated using the neoclassical transport theory.
