Modelling of JT-60U Detached Divertor Plasma using SONIC code
The characteristics of the JT-60U detached divertor plasma in the SONIC simulation are investigated. With increasing mid-plane density, the electron temperature at the divertor decreases and the ion flux to the divertor plate increases. At higher densities, the temperature becomes less than 1 eV. However, rollover of the ion flux at the divertor plate, which is a characteristic of the detachmen...
متن کاملAnalytical calculations for impurity seeded partially detached divertor conditions
A simple analytical formula for the impurity seeded partially detached divertor operational point has been developed using 1D modelling. The inclusion of charge exchange momentum loss terms improves the 1D modelling for ASDEX Upgrade conditions and its extrapolation to larger devices. The investigations are concentrated around a partially detached divertor working point of low heat flux and an ...
متن کاملKinetic Modelling of Impurity Transport in Detached Plasma for Integrated Divertor Simulation with SONIC (SOLDOR/NEUT2D/IMPMC/EDDY)
An integrated divertor simulation code SONIC has been developed. The self-consistent coupling of an MC impurity code IMPMC to a divertor code SOLDOR/NEUT2D is succeeded by overcoming the intrinsic problems of Monte Carlo (MC) modelling for impurity transport. MC modelling for impurity transport is required in order to take into account the kinetic effect and the complex dissociation processes o...
متن کاملPFC / JA - 94 - 012 Plasma - Surface Interactions in the Alcator C - Mod Tokamak
Alcator C-Mod is a high-field tokamak with which experiments were initiated in April 1993. The divertor and the first-wall have plasma-facing surfaces of molybdenum. The divertor has a configuration which is closed in comparison to other, currently operating tokamaks. The combination of divertor geometry and high field (density) make Alcator C-Mod an ideal experiment to investigate dissipative ...
متن کاملPFC / JA - 94 - 35 Performance of the Alcator C - Mod Closed Divertor in Ohmically Heated Plasmas
Alcator C-Mod operation with a single null closed divertor produces clean, Zeff <1.3 plasmas and two dissipative divertor regimes. For ;1e > 0.7x 1020 m3 the divertor plasma is highly recycling and radiative with high densities and low temperatures near the strike points. If the temperature near the target plates drops to <5 eV, this plasma detaches from the plates over most of their surfaces. ...
