Basic physical processes and reduced models for plasma detachment
PC Stangeby - Plasma Physics and Controlled Fusion, 2018 - iopscience.iop.org
The divertor of a tokamak reactor will have to satisfy a number of critical constraints, the first
of which is that the divertor targets not fail due to excessive heating or sputter-erosion. This …

Turbulence driven widening of the near-SOL power width in ASDEX Upgrade H-Mode discharges
Divertor heat flux data from infra red (IR) from various tokamaks in H-Mode regime show that
the power width, $\lambda_ {q} $, scales approximately like 1.6 (R/a) ρ s, pol. However, the …
