Note: Multi-point measurement of |B| in the gas-dynamic trap with a spectral motional Stark effect diagnostic.
An upgraded spectral motional Stark effect diagnostic has been installed on the gas-dynamic trap (GDT) experiment to enable spatially resolved measurement of |B|. A new low-noise charge-coupled device detector, combined with enhancements of the diagnostic neutral beam, allows single-shot profile measurements. Previously only single-point motional Stark effect measurements were possible, and det...
متن کاملA high spatial resolution Stokes polarimeter for motional Stark effect imaging.
We describe an enhanced temporally switched interfero-polarimeter that has been successfully deployed for high spatial resolution motional Stark effect imaging on the KSTAR superconducting tokamak. The system utilizes dual switching ferroelectric liquid crystal waveplates to image the full Stokes vector of elliptically polarized and Doppler-shifted Stark-Zeeman Balmer-alpha emission from high e...
متن کاملMotional Stark Effect Measurements of the Local Magnetic Field in High Temperature Fusion Plasmas
The utilization of the Motional Stark Effect (MSE) experienced by the neutral hydrogen or deuterium injected into magnetically confined high temperature plasmas is a well established technique to infer the internal magnetic field distribution of fusion experiments. The different properties of the Stark multiplet allow inferring, both the magnetic field strength and the orientation of the magnet...
متن کاملOptical coherence-based techniques for motional Stark effect measurements of magnetic field pitch angle
The motional Stark effect measurement of magnetic field pitch angle in tokamaks is a mature and powerful technique for estimating plasma current density in tokamaks. However, its range of applicability is limited by the requirement that σ andπ manifolds are spectrally sufficiently well separated (high magnetic fields, high beam energies) to ensure adequate net polarization for a successful meas...
متن کامل1 OV / 3 - 3 Overview of Physics Results from MAST
Major plant and diagnostic developments on MAST have enabled important advances in support of ITER, definition of a component test facility (CTF) and the clarification of underlying tokamak physics. For example, L-H transition studies benefit from high spatial and temporal resolution measurements of pedestal profile evolution (temperature, density and radial electric field) and in support of pe...
