Doppler Backscattering hardware has been used to detect the density peak in C-2W FRC plasmas from transmission/reflection transitions.
Main result: The peak density reconstructed from FIR Interferometry (via ABEL inversion) is on average 20-25% lower than the peak density determined via DBS.

TAE’s C-2W FRC shows key differences in fluctuation properties between hydrogen and deuterium plasmas, with increased magnetic fluctuations in FRC and low ion-scale fluctuations in the core. These findings, consistent with simulations, inform the design of diagnostics for the upcoming Copernicus device.

Microwave-based diagnostic techniques have major advantages in
high temperature/burning plasmas more robust that optical diagnostics:
– no in-vessel / first wall optical windows/mirrors needed
