摘要: This paper describes a detailed examination of the effects relatively small pulsed deuterium gas puff on edge plasma and turbulence in NSTX. caused little or no change line-averaged density total stored energy, electron temperature up to time peak puff. The radial profile Dα light emission within this did not vary significantly over its rise fall, implying that these puffs perturb local turbulence. These measurements are compared with modeling by DEGAS 2, UEDGE, simplified estimates for expected
