Abstract
Since the early days of Fusion and Tokamak research, the optical properties of Plasmas in the Far Infrared Radiation (FIR) and submillimeter waves range (100-2000 GHz, and beyond) have provided one of the most important plasma diagnostic tool set, covering Interferometry, Polarimetry, Reflectometry and Electron Cyclotron Emission. In 2010 the FIR diagnostics world was ready to move on to THz-TDS spectroscopy applications and to this end ENEA Frascati joined forces with Oxford Clarendon Laboratory, creating a rare and successful synergy between two independent areas of research. The methods and techniques successfully applied in the study of semiconductors and materials have been transferred to the realm of plasma diagnostics. A brief contextual review of FIR diagnostics, their evolution towards THz-TDS and the perspective applications for Nuclear Fusion and other areas of plasma physics will be given in this seminar.
