This category works to make generic, long-term improvements in the operation and reliability of ICRF systems for use in present-day or future ICRF heating and current drive installations.

High-voltage breakdown studies : Carried out in collaboration with the Max Planck Institüt für Plasmaphysik in Garching, Germany, to study and understand the limitations caused by high-voltage breakdown in antennas exposed to a plasma environment, and to figure out how to improve the voltage limits.

Arc localization studies: To develop quick, reliable ways to determine the location of arcs in ICRF components in typical systems. Advanced launchers: New ICRF antenna concepts, which may have significant advantages over the conventional strap launchers, are developed and tested. Advanced tuning and matching: To develop and test new, improved techniques for providing power to the ICRF antennas during changes in plasma conditions. System modeling: Calculate the properties of complicated, coupled rf systems, and their interaction with the plasma. Plasma Sources - make high-density plasma with rf. Facilities: Provides chambers with vacuum, plasma, and magnetic field for testing of rf components.
