چکیده

Numerical study of the SOL in the T-11M with the use of a combination of edge and core plasma codes, SOL-DINA and DINA is carried out. Modeling results are compared with experiment for ohmic heating discharges with Li and Carbon limiter in T-11M tokamak. Temperatures, electron density and lithium distribution in SOL are compared. Values for anomalous radial diffusion coefficients of Li ions and heat conductivity are tested against experiment.

Overview of the Alps Program

The US Advanced Limiter-divertor Plasma-facing Systems (ALPS) program is developing the science of liquid metal surface divertors for near and long term tokamaks. These systems may help solve the demanding heat removal, particle removal, and erosion issues of fusion plasma/surface interactions. ALPS combines tokamak experiments, lab experiments, and modeling. We are designing both static and fl...

An optimal penalty method for an hyperbolic system modeling the edge plasma transport in a tokamak

The penalization method is used to take account of obstacles, such as the limiter, in a tokamak. Because of the magnetic confinement of the plasma in a tokamak, the transport occurs essentially in the direction parallel to the magnetic field lines. We study a 1D nonlinear hyperbolic system as a simplified model of the plasma transport in the area close to the wall. A penalization which cuts the...

Numerical Studies and Simulation of the Lower Hybrid Waves Current Drive by using Fokker – Planck Equation in NSST and HT-7 Tokamaks

Recent experiments on the spherical tokamak have discovered the conditions to create a powerful plasma and ensure easy shaping and amplification of stability, high bootstrap current and confinement energy. The spherical tours (ST) fusion energy development path is complementary to the tokamak burning plasma experiment such as NSTX and higher toroidal beta regimes and improves the design of a po...

Experiments with Lithium Gettering in T-10 Tokamak

The two experimental campaign with lithium gettering of the T-10 chamber were carried out. The experiments were aimed to prove the lithium abilities to obtain high performance discharges with lithium cover of the wall and limiters with reduced recycling of the working gas and the impurities level in ohmic and heated with the high ECR power tokamak discharges. The second goal of the T-10 experim...
