| Abstract: | The particle transport during pellet fuelling and MBI in the HL-1M tokamak is investigated.Assuming the operator in transport equation is linear,we emphasize on investigating the solution of transport equation.Particle source function was fit in with a curve under steady state gas puffing.By means of gas puffing modulation,diffusion coefficient and inward velocity were calculated under gas puffing and MBI modulation experiment on the HL-1M tokamak.From long density attenuation times,the diffusion coefficient and inward velocity were calculated after pellet injection.The results show that the MBI and pellet injection improve the transport property of plasma particles. |
