Results from the DITE bundle divertor with fuelling in the divertor
Journal of Nuclear Materials, 1984The DITE bundle divertor MkII has been operated with high power neutral beam injection, up to 2.1 MW, and with gaseous fuelling in the divertor. Discharges with good confinement have been used to study the properties of the plasma exhaust channel in the presence of a high density of neutral molecules in the divertor, up to ~ 1 ×1021 m−3. An inner layer

A Slot Divertor for Tokamaks with High Divertor Heat Loads
Fusion Technology, 1990AbstractA new divertor configuration is suggested as a possible solution to the problems of high heat flux and erosion at the divertors in large high-power tokamaks. The proposed configuration is a toroidally symmetrical slot in the divertor that allows part of the edge plasma and most of its power to enter a cavity in a thin annular sheet.

The poloidal divertor field amplifiers for the JET pump divertor
Proceedings of 16th International Symposium on Fusion Engineering, 2002Four new amplifiers have been procured to feed the new divertor field coils of JET. They have been operated successfully since the beginning of 94. The paper presents their main characteristics and the operational experience acquired during experimental campaigns.

15th IEEE/NPSS Symposium. Fusion Engineering, 2002
The ITER divertor design is based on the high density exhaust concept of reducing peak heat fluxes falling on the divertor plates. The power is transferred from the edge plasma to the walls of the divertor chamber by atomic and molecular processes such as radiation, charge exchange, recombination, and gas conduction before it can reach tile divertor ...

Kinetic Divertor Modeling [PDF]
, 2011 The coupled dynamics and kinetics between gas and plasma in the divertor region is studied by means of a one-dimensional Particle in Cell-Direct Simulation Monte Carlo (PIC-DSMC) model. In particular, the collision-induced vibrational excitation/relaxation of H2 molecules and particle-surface interaction (vibrational relaxation and recombinative ...

Plasma recombination and molecular effects in tokamak divertors and divertor simulators
Physics of Plasmas, 1997Analysis of the experimental data from tokamaks and linear divertor simulators leads to the conclusion that plasma recombination is a crucial element of plasma detachment. Different mechanisms of plasma recombination relevant to the experimental conditions of the tokamak scrape-off layer (SOL) and divertor simulators are considered.

ENGINEERING DESIGN OF THE ITER DIVERTOR
1997This paper reports on the status of the mechanical and thermo-hydraulic design of the divertor. It describes the current design of the divertor plasma facing components (PFCs), and the steel structure (cassette body) that supports these PFCs.
