Investigation of Radial Particle Transport in the GAMMA 10 Tandem Mirror

Radial particle transport in GAMMA 10 was investigated under a quasi-steady state condition plasma. The transport analysis was carried out with changing the boundary conditions, in order to reconstruct the density profile which is consistent with the measured data. From the above result, the best fit profile to the measured one was obtained with the diffusivity of 0.57 m²/s. The particle diffusivity in an additional gas puffing experiment was estimated. The result of the transport analysis was also compared with the diffusion coefficient expected from classical diffusion processes.
