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...
متن کاملAbsorption of lower hybrid waves in the scrape off layer of a diverted tokamak
The goal of the Lower Hybrid Current Drive (LHCD) system on the Alcator C-Mod tokamak is to investigate current profile control under plasma conditions relevant to future devices such as ITER and DEMO. Experimental observations of an LHCD " density limit " for C-Mod are presented in this paper. Bremsstrahlung emission from relativistic fast electrons in the core plasma drops suddenly above line...
متن کاملگرم کردن پلاسما با امواج برنشتاین الکترونی از طریق واگردانی امواج عادی و فراعادی درلایه UHR
Magnetically confined plasma can be heated with high power microwave sources. In spherical torus the electron plasma frequency exeeds the electron cyclotron frequency (EC) and, as a consequence, electromagnetic waves at fundamental and low harmonic EC cannot propagate within the plasma. In contrast, electron Bernstein waves (EBWs) readily propagate in spherical torus plasma and are absorbed str...
متن کاملIntermittent fluctuations in the TCV scrape-off layer
Probe measurements in the scrape-off layer of tokamak plasmas show that the ion saturation current signal is dominated by large amplitude bursts. Analysis of data time series from tokamak á configuration variable of unprecedented duration reveals that both burst amplitudes and waiting times are exponentially distributed. The average burst wave form has an exponential shape with a characteristic...
متن کاملThe Scrape - Off - Layer in Alcator C - Mod – Transport , Turbulence , and Flows
Research on the scrape-off-layer plasma of the Alcator C-Mod Tokamak is reviewed. The research has focused on understanding the transport of energy and particles both parallel and perpendicular to the magnetic field. Large differences between the inboard, high-field side scrape-off-layer and the outboard, low-field side are found. On the outboard side large levels of anomalous cross-field trans...
