Description

Distribution of particle recycling from limiter and wall in an ohmically heated tokamak plasma was investigated by hydrogen alpha line λ 6562.8 A) measurements in TBR-1. The results show that the intensity profiles are toroidally and poloidally asymmetric. The peak value of Hα emission occurs in the limiter and then decays exponentially along the toroidal direction. The decay angle is less than 200 C. The poloidal asymmetry, at the plasma edge can be represented by a factor (1+β cosθ), with β being about 0.8 in this experiment. A Linear relation between recycling source and electron density is confirmed. Particle confinement times and recycling rates are also discussed. (author). 13 refs, 15 figs, 1 tab
