Abstract

Design features of the ICRF (ion cyclotron range of frequencies) fast-wave antenna to be used on the Alcator C-MOD tokamak are described. Initially, a movable, single-current-strap antenna will be used. A detailed study of the antenna performance was carried out using an antenna-plasma coupling code. Mechanical strength against disruption forces was a major consideration in the antenna design. Analyses show that the present design is mechanically and thermally satisfactory. An optimized configuration being planned for future experiments and having two double-current-strap antennas is also described
