Lower Hybrid Experiments on MST
Current drive using RF waves has been proposed as a means to reduce the tearing fluctuations responsible for anomalous energy transport in the RFP. A traveling wave antenna operating at 800 MHz is being used to launch lower hybrid waves into MST to assess the feasibility of this approach. Parameter studies show that edge density is a major factor in antenna/plasma coupling. Gas puffing near the...
متن کاملMeasurement of fast electron transport by lower hybrid modulation experiments in Alcator C-Mod
The Lower Hybrid Current Drive (LHCD) system on Alcator C-Mod can produce spectra with a wide range of peak parallel refractive index (n||). An experiment in which LH power is square-wave modulated on a time scale much faster than the current relaxation time does not significantly alter the poloidal magnetic field inside the plasma and thus allows for realistic modeling and consistent plasma co...
متن کاملInvestigation of lower hybrid physics through power modulation experiments on Alcator C-Mod
Lower hybrid current drive (LHCD) is an attractive tool for off-axis current profile control in magneticly confined tokamak plasmas and burning plasmas (ITER), because of its high current drive efficiency. The LHCD system on Alcator C-Mod operates at 4.6 GHz, with ∼ 1 MW of coupled power, and can produce a wide range of launched parallel refractive index (n ||) spectra. A 32 chord, perpendicula...
متن کاملEX/P6-19 Lower Hybrid and Electron Bernstein Wave Current Drive Experiments in MST
Inductive current profile modification in MST has been successful in reducing fluctuations and transport but is transient and radially non-localized. Current profile control with rf waves offers steady and more precise control. Studies of lower hybrid wave and electron Bernstein wave injection are underway. The lower hybrid antenna has coupled 125 kW to the plasma. Hard x-ray emission with ener...
