The addition of laser-induced fluorescence to
the traditional Motional Stark Effect concept holds the promise of
allowing direct magnetic field magnitude as well as pitch angle
measurements. This would enable determination of the plasma
pressure and current profiles. Nova Photonics is engaged in the
development of this concept. The system is based on a carefully
engineered diagnostic neutral beam, and would run independently of
a heating beam on an experiment. This would also enable study of
phenomena in the absence of heating beams. This development work
has yielded interesting atomic physics results as well.
