First Cross-Polarization Scattering Data in C-2W
§ Launching X-mode and receiving O-mode in backscattering geometry with one test channel
§ CPS signal is ~ 7x smaller than DBS signal - within expectations CPS signal is well above noise level
§ Probing radius r (cut-off layer) is here in the outer FRC core inside Rs

B radial profile will provide estimate of
electromagnetic turbulent transport and allow benchmarking Gyrokinetic/kinetic simulations
