Abstract

The toroidal flow was observed in a hot electron mode plasma. The flow was antiparallel to the E^{r X B} drift direction. This was in contrast to the spontaneous toroidal flow in the direction parallel to the direction of drift in tokamak plasmas. The toroidal flow was large enough to overcome the toroidal flow driven by a tangentially injected neutral beam at the transport barrier.
