摘要：

A versatile combination Doppler backscattering and Cross-Polarization Scattering (CPS) diagnostic for the C-2W beam-driven field-reversed configuration is described. This system is capable of measuring density fluctuations and perpendicular magnetic field fluctuations across a wide wavenumber range ( 2.5 <= k theta rho(s) <= 50), with typical resolution Delta k(theta)/k(theta) <= 0.4-0.8. Four tunable frequencies (26 GHz <= f <= 60 GHz corresponding to plasma cut-off densities 0.8 x 10(19) <= n(e) <= 4.4 x 10(19) m(-3)) are launched via quasi-optical beam combiners/polarizers and an adjustable parabolic focusing mirror selecting the beam incidence angle. GENRAY ray tracing shows that the incident O-mode and backscattered CPS X-mode beam trajectories for C-2W plasma parameters nearly overlap, allowing simultaneous detection of (n) over tilde and (B) over tilde (r) or (B) over tilde (theta) from essentially the same scattering volume.
