Multi-channel Doppler backscattering measurements in the C-2 field reversed configuration

August 2014 | L. Schmitz | Review of Scientific Instruments | Paper

A versatile heterodyne Doppler Backscattering (DBS) system is used to measure density fluctuation levels (in the wavenumber range kρs ≤ 50), and the toroidal E × B flow velocity in the C-2 Field-Reversed Configuration (FRC).
