Abstract:

The development of detector arrays for two dimensional imaging of electron cyclotron emission is essential for the investigation of heat transport and turbulent confinement in fusion plasmas. A new approach to imaging techniques is presented in which the quasi-optical coupling of pumping power is substituted by a direct on-chip distribution scheme using a fully MMIC multichannel mixer circuit. The system makes use of a subharmonic mixer array designed in multisubstrate technology to perform 6 to 8 dB conversion loss. Aperture coupled patch antennas are used for the reception of plasma signal, whereas pumping power is fed to the mixer through a waveguide-microstrip transition.
