Description
Summary:The Synthetic Aperture Microwave Imaging diagnostic (SAMI) has been operating on the MAST experiment since 2011. It has provided the first 2D images of B-X-O mode conversion windows and showed the feasibility of conducting 2D Doppler back-scattering experiments. The diagnostic heavily relies on field programmable gate arrays (FPGAs) to conduct its work. Recent successes and newly gained experience with the diagnostic has led us to modify it. The enhancements will enable pitch angle profile measurements, O and X mode separation and the continuous acquisition of 2D DBS data. The diagnostic has also been installed on the NSTX-U and is acquiring data since May 2016.
