UC Davis PDG:Microwave Imaging Reflectometry on TEXTOR

 

 
 

UC Davis, in collaboration with the FOM Instituut voor Plasmafysica 'Rijnhuizen' and PPPL in Princeton , installed a prototype 8 channel MIR system  to spatially resolve ne fluctuations on the TEXTOR tokamak. This system was operating at 83-87 GHz and reflecting from the X-mode cutoff.  We will install a new Microwave Imaging reflectometric system on the TEXTOR tokamak in Germany in, 2002. We plan to use a  6-10 channel system to collect data on TEXTOR plasmas.

The UC Davis Microwave Imaging Reflectometry system shares a port with a multipoint Thomson scattering system, thereby providing a calibration for the responsivity of the imaging channels.

Introduction and background of Microwave Imaging Reflectometry system

The features of the Mivrowave Imaging Reflectometry diagnostics derive from the use of wideband, low cost monolithic and hybrid Schottky diode mixer arrays. Follow the links below to learn more about both the technology and the techniques employed in MIR.
