ECCD system design activities for JA DEMO

Abstract

ECCD system design activities for JA DEMO is in progress. Activities contains physical analysis, launcher design, and RF power plant design. The physical analysis activity explores various approaches to enhance ECCD efficiency. The RF power plant design activity produced a conceptual design of a 100 MW class RF power plant. The launcher design activity presented the upper and equatorial launcher port of the JA DEMO tokamak vacuum vessel and analyzed the ECCD operation of each launcher. The result is the achievement of RF power deposition at the core of plasma for ECCD by selecting the proper injection angle and frequency.
