Antonio Silva has been a member of the Microwave Group at Instituto de Plasmas e Fusão Nuclear (IPFN) since 1991, and part of the ASDEX Upgrade team since 1992. His current work and research interests focus on the development of advanced plasma diagnostic systems, particularly reflectometry and Collective Thomson Scattering. In 1991, he was invited to design a reflectometry system for the ASDEX Upgrade. This system was the first to enable measurements from both the Low Field Side (LFS) and the High Field Side (HFS) of the tokamak. This unique configuration made it possible, in 2011, to conduct the first experiments on Reflectometry Plasma Position, leading to the first-ever demonstration of the feasibility of using O-mode reflectometry as an alternative to conventional magnetic diagnostics for fusion plasma position control. All over the years the author has been involved in several projects as Principal Investigator, Task coordinator or Researcher. FMCW reflectometers were developed and installed on MAST UK, TCA/Br Brazil, COMPASS IPP.CR Czech Republic, ICRH antenna X-mode reflectometer on ASDEX Upgrade IPP Germany which was the subject of a PhD thesis supervised by the author. The author was the Principal Investigator of the WPJET14 JET Enhancements: Correlation Reflectometer Upgrade at the UK. The objective was to extend the measuring capabilities of the existing correlation, in preparation for D-T campaigns, by adding additional frequency bands (V band 50 to 75 GHz) and (F band 90 to 140 GHz). The author was strongly involved on the design of the Plasma Position Reflectometer (PPR) for ITER. His responsibilities included the design of the back-end and front-end electronics; design and testing of the in-vessel probing antennas. Since 2017 the author is task coordinator for the “DEMO diagnostic R&D: microwave diagnostics”. This includes the design of the transmission lines, design of the antennas, define the numbers of probing views and frequency bands to be used, define the receiver parameters in particular minimum sensitivity and the integration of the system on DEMO. The author is involved on the design of the antennas and prototyping testing for the Divertor Tokamak Testing (DTT).
