Abstract
Systems, devices and methods that facilitate non-intrusive measurement and validation of field-reversal of a core plasma by combining DFSS and blended Zeeman concepts (i.e., sub-Doppler circular dichroism spectroscopy).
Claims19
A method for measuring the magnetic field direction in a field-reversed configuration (FRC) plasma comprising,
- generating linearly polarized probe and pump beams, and
- counter-propagating the pump and probe beams along a longitudinal axis of a confinement vessel containing an FRC plasma.
A sub-Doppler circular dichroism spectroscopy system for measuring field-reversal in an FRC plasma comprising
- a beam source for generating a beam, and
- a plurality of optical components optically coupled and configured to generate linearly polarized probe and pump beams, and counter-propagate the pump and probe beams along a longitudinal axis of a confinement vessel containing an FRC plasma.
