Particle transport simulations based on selfconsistency of pressure profiles in tokamaks

Particle transport simulations based on selfconsistency of pressure profiles in tokamaks

Simulation of particle and heat transport was performed with the ASTRA code. The equations for the electron temperature and density, ion temperature and current diffusion were solved. For the heat transport we used the canonical profiles model. Three T-10 pulses with toroidal magnetic field 2.5...
