Quasilinear Transport Fluxes Driven by Electrostatic Microinstabilities in Tokamaks
Abstract Quasilinear transport fluxes driven by microinstabilites in weakly-collisional tokamak plasmas are calculated by a semi-analytical approach based on a solution of the gyrokinetic equation, where collisions are modelled by a Lorentz operator. Scalings with collisionality, magnetic drift frequency, diamagnetic frequency and ratio of the density and temperature scale lengths have been det...
متن کاملNonlinear flow generation by electrostatic turbulence in tokamaks
Global gyrokinetic simulations have revealed an important nonlinear flow generation process due to the residual stress produced by electrostatic turbulence of ion temperature gradient ITG modes and trapped electron modes TEMs . In collisionless TEM CTEM turbulence, nonlinear residual stress generation by both the fluctuation intensity and the intensity gradient in the presence of broken symmetr...
متن کامل1 TH / P 4 - 5 Mitigation of ELMs and Disruptions by Pellet Injection
Deuterium, impurity and impurity doped pellets are studied in light of their use for ELM and disruption mitigation. Based on ELM pace making studies at ASDEX Upgrade and JET, the minimum pellet size required to cause an ELM, has been estimated in ITER for the foreseen pellet velocities. Concerning disruption mitigation studies the number of runaways is determined for JET like plasmas for deuter...
