Japan-US Collaboration on ICRF Heating and Current Drive Experiments and Modeling
The ICRF heating experiments on the Alcator C-Mod Tokamak at MIT have been highly successful. With the additional power and current drive capabilities currently being added in collaboration with PPPL (Princeton Plasma Physics Laboratory), the emphasis of research will shift toward steady-state advanced Tokamak experiments using current drive and profile control. MIT is already preparing the infrastructure necessary to support remote collaborators.
Participation in these experiments by the University of Tokyo group, including planning of experiments, real-time participation, and data analysis, became possible with the increased bandwidth provided by APAN. The University of Tokyo group, collaborating with MIT physicists, performed theoretical modeling of various heating and current drive scenarios in 1998. The results indicate potential usefulness of the harmonic fast wave for current drive in both conventional and spherical Tokamaks.
