摘要：
Results are obtained, for the first time in a major tokamak plasma, of the spatial electric field structure of a launched fast magnetosonic wave (FW). The FW launch directionality necessary for current drive has been confirmed at a position close to the FW antenna. The FW electric field profile is determined using X-mode reflectometry. Electric field profiles, calculated using a full-wave numerical code, exhibit many features common to the experimental results. However, differences remain regarding density dependence that suggest alternative damping mechanisms may exist.
