The multichannel motional Stark effect diagnostic on TFTR

Improved spectral analysis for the motional Stark effect diagnostic.

The magnetic pitch angle and the magnitude from reversed field pinch plasmas in the Madison symmetric torus (MST) have been routinely obtained from fully resolved motional Stark effect (MSE) spectrum analyses. Recently, the spectrum fit procedure has been improved by initializing and constraining the fit parameters based on the MSE model in the atomic data and analysis structure. A collisional-...

Two-point motional Stark effect diagnostic for Madison Symmetric Torus.

A high-precision spectral motional Stark effect (MSE) diagnostic provides internal magnetic field measurements for Madison Symmetric Torus (MST) plasmas. Currently, MST uses two spatial views--on the magnetic axis and on the midminor (off-axis) radius, the latter added recently. A new analysis scheme has been developed to infer both the pitch angle and the magnitude of the magnetic field from M...

Measurement of the Plasma Radial Electric Field by the Motional Stark Effect Diagnostic on JET Plasmas

Progress on the motional Stark effect with laser-induced fluorescence diagnostic „invited..

The motional Stark effect with laser-induced fluorescence MSE-LIF diagnostic is presently under development as a new technique for measuring magnetic field pitch angle and magnitude in plasmas in a wide range of conditions. The technique is based on the observation of LIF from the set of H-alpha transitions in a diagnostic hydrogen neutral beam. As the beam passes at a high velocity through a b...
