TL;DR: Some of the remaining crucial plasma edge physics and plasma-material interaction issues of the ITER tokamak are discussed in this paper, using either modelling or projections of experimental results from existing TOKAMAK operation or relevant laboratory simulations.

TL;DR: In this paper, the authors studied the power-decay length of the divertor tokamak ASDEX upgrade and showed that the drift-wave dynamics in the inner divertor and the outer divertor can be modelled by a gyro-fluid code and point to the dominance of drift waves.
