1 Studies of Plasma Detachment Using a One Dimensional Model for Divertor Operation

by R. A. Vesey A, D. E. Post A, G. Bateman A
"... To characterize the conditions required to reach advanced divertor regimes, a one-dimensional computational model has been developed based on a coordinate transformation to incorporate two-dimensional effects. This model includes transport of ions, two species each of atoms and molecules, momentum, ..."

Operating Windows of Pebble Divertor

by K. Matsuhiro, M. Isobe, Y. Ohtsuka, Y. Ueda, M. Nishikawa
"... Abstract. A marked feature of the pebble divertor is an effect by use of functional multi-layer coated pebble, which consists of a surface plasma facing layer, an intermediate tritium permeation barrier layer, and a kernel for heat removal. The dimensions, structure and the irradiation conditions of ..."

Experimental Divertor Similarity Database Parameters

by I. H. Hutchinson, B. Labombard, B. Lipschultz , 1995
"... A set of experimentally-determined dimensionless parameters is proposed for characterizing the regime of divertor operation. The objective is to be able to compare as unambiguously as possible the operation of different divertors and to understand what physical similarities and differences they repr ..."

INITIAL OPERATION OF THE DIVERTOR THOMSON SCATTERING

by The Divertor, Thomson Scattering , 1996
"... The first Thomson scattering measurements of ne and T e in the divertor region of a tokamak are reported. These data are used as input to boundary physics codes such as UEDGE and DEGAS and to benchmark the predictive capabilities of these codes. These measurements have also contributed to the charac ..."

Neutral gas modeling in divertors∗

by Charles F. F. Karney
"... The divertor is one of the critical components in a tokamak reactor. It must absorb the α-particle power and particle flux and any auxiliary heating power; it must permit the removal of the helium ash so that the hydrogen fuel in not diluted. The major constraints on the operation of the divertor ar ..."
