ADVANCED VIEWS IN FAR INFRARED SPECTROSCOPY APPLICATIONS FOR ECE MEASUREMENTS

The diagnostic potential of ECE [A. Costley, Diagnostics for Fusion Reactor Conditions (Varenna 1982), EUR 8351-I, p. 129&149] has been studied in almost every aspect since the dawn of Fusion experiments. It represents currently an almost unique opportunity to provide an established diagnostic system for the next step experiments, but it still has a vast potential to explore. In this heuristic work we introduce a novel approach to physics interpretation, suggesting ECE energy transport between harmonics which in certain plasma regimes can also be relevant from the plasma point of view. In addition we discuss the implementation of an unconventional hybrid hardware solution to extend the capability of the systems by using mixed quasi-optical and electronic techniques.
