The magnetic structure of FRCs cannot be measured directly by existing diagnostics. A new tool “Grushenka” finds the structure based on magnetic measurements at the vessel wall.

Ion-scale modes have been shown to be stable in the C-2/C-2FRC core, in agreement with initial gyrokinetic simulation results, with a characteristic inverted toroidal wavenumber spectrum confirmed via Doppler Backscattering (DBS) measurements.

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.
