Investigation of atomic and molecular rates in plasma-edge simulations through experiment-simulation comparisons

  title={Investigation of atomic and molecular rates in plasma-edge simulations through experiment-simulation comparisons},
  author={A. C. Williams},
Divertor plasma detachment is likely needed for the function of magnetically confined nuclear fusion. It greatly reduces the particle and heat flux incident on a target, and thus reduces the sputtering and heat loading on the target. It is therefore advantageous to have accurate simulations of plasma behaviour in the divertor to design future Tokamak divertors. A common simulation package used for this purpose is SOLPS-ITER, which has previously been observed to be underestimating the…

The role of plasma-molecule interactions on power and particle balance during detachment on the TCV tokamak

This paper shows experimental results from the TCV tokamak that indicate plasma-molecule interactions involving D2+ and possibly D− play an important role as sinks of energy (through hydrogenic

A novel hydrogenic spectroscopic technique for inferring the role of plasma-molecule interaction on power and particle balance during detached conditions

Detachment, an important mechanism for reducing target heat deposition, is achieved through reductions in power, particle and momentum; which are induced through plasma-atom and plasma-molecule

A study of the influence of plasma–molecule interactions on particle balance during detachment

In this work we provide experimental insights into the impact of plasma-molecule interactions on the target ion flux decrease during divertor detachment achieved through a core density ramp in the

Separating the roles of magnetic topology and neutral trapping in modifying the detachment threshold for TCV

Total flux expansion, a divertor magnetic topology design choice embodied in the Super-X divertor, is predicted through simple analytic models and SOLPS calculations to reduce the plasma and impurity

SOLPS-ITER simulations of the TCV divertor upgrade

The effect of the upcoming TCV divertor upgrade on the distribution of neutrals and the onset of detachment is studied using 2D transport code simulations. The divertor upgrade is centered around the
