C-2U has achieved steady-state operation of advanced beam driven FRCs using neutral beam injection and edge biasing.
Improved density profile measurements in the C-2U advanced beam-driven Field-Reversed Configuration (FRC) plasmas
August 2016 | M. Beall | Review of Scientific Instruments | Paper
In the prior C-2 experiment, electron density was measured using a two-color 6-chord CO2/HeNe interferometer. Analysis shows that high-frequency common mode phase noise can be reduced by a factor of 3 by constructing a reference chord.
