Inward particle transport at high collisionality in the EAST tokamak
Journal article, 2013

We have simulated two discharges in the tokamak EAST at ASIPP, Hefei. Particular focus has been put on the particle transport since EAST has a peaked density profile with only edge fuelling. The turbulent particle pinch has not been assumed to be strong in such strongly collisional plasmas as that in EAST. However, as it turned out, there is an increase in the particle pinch for high collisionality in our model. This was verified by turning collisions on and off in the simulations. Overall good agreement was found.
