VUV Spectral Line Emission Measurements in the TCABR Tokamak
VUV spectrometry higher diffraction order spectra tokamak ion temperature multi-channel detector
2010/7/5
The study of tokamak plasma light emissions in the vacuum ultraviolet (VUV) region is an important subject since many impurity spectral emissions are present in this region. These spectral emissions c...
Electron Density Measurements from Right-Hand Cutoff of ECE in the TCABR Tokamak
Electron Density Measurements Right-Hand ECE the TCABR Tokamak
2010/10/27
In tokamak machines with low toroidal magnetic fields and high plasma densities, the accessibility conditions impose restrictions to the detection of the Electron Cyclotron Emission ( ECE ). In these ...
A millimeter/microwave detection system, in operation in the TCABR Tokamak is described. The system is used for electron cyclotron measurements. The main part of the system is a heterodyne sweeping ra...
Fast Opening Gas Valve for the TCABR Pellet Injector
Fast Opening Gas Valve the TCABR Pellet Injector
2010/10/27
Fast acting gas valves that operate between two very different pressure environments, which may differ in several orders of magnitude, are not available commercially and, therefore, they must be speci...
Identification of the Alfvén Wave Resonances in the TCABR Tokamak by the Microwave Reflectometry
the Alfvén Wave Resonances the TCABR Tokamak the Microwave Reflectometry
2010/10/27
The experimental results on the Alfv´en mode structure identification by the microwave reflectometry in TCABR tokamak are presented. The knowledge of the spatial spectrum of the excited waves is...
Using two dimensional numerical codes, we show that the direct electron heating found with electron cyclotron emission (ECE) radiometry is related to local Alfv´en wave resonances in Tokamak Cha...
Electron Cyclotron Emission Simulation from TCABR Plasmas
Electron Cyclotron Emission TCABR Plasmas
2010/10/27
Electron cyclotron emission due to electrons described by a particular distribution function has been studied. The latter presents an extended tail generated by the interaction of the Lower Hybrid wav...
