Design of a Microwave Frequency Sweep Interferometer for Plasma Density Measurements in Ecr Ion Sources∗
Electron Cyclotron Resonance Ion Sources (ECRIS) are among the candidates to support the growing request of intense beams of multicharged ions. Their further development is related to the availability of new diagnostic tools, nowadays consisting of few types only of devices designed on purpose for such compact machines. Microwave Interferometry is a non-invasive method for plasma diagnostics an...
متن کاملElectronically swept millimeter-wave interferometer for spatially resolved measurement of plasma electron density.
We report the development and initial implementation of what we believe to be a new rapid- spatial-scan millimeter-wave interferometer for plasma density measurements. The fast scan is effected by electronic frequency sweeping of a wideband (180-280 GHz) backward-wave oscillator whose output is focused onto a fixed blazed diffraction grating. The system, which augments the rotating-grating scan...

We report the development and initial implementation of a new rapidspatial-scan millimetre-wave interferometer for plasma density measurements. The fast scan is effected by electronic frequency sweeping of a wide-band (180-280GHz) backward-wave oscillator (BWO) whose output is focussed onto a fixed blazed diffraction grating. The system, which augments the rotating-grating scanned multi-view H-...
متن کاملFizeau interferometer for measurement of plasma electron current
A high-resolution, vertically viewing far-infrared polarimeter-interferometer system is currently used on the Madison symmetric torus (MST) reversed-field pinch (RFP) to measure the plasma electron density and toroidal current density via Faraday rotation. In this article, we propose a scheme to measure the well-known Fizeau effect, whereby through modest modification of the existing apparatus,...
متن کاملPerturbing microwave beams by plasma density fluctuations
The propagation of microwaves across a turbulent plasma density layer is investigated with fullwave simulations. To properly represent a fusion edge-plasma, drift-wave turbulence is considered based on the Hasegawa-Wakatani model. Scattering and broadening of a microwave beam whose amplitude distribution is of Gaussian shape is studied in detail as a function of certain turbulence properties. P...
