In the DII-A lower hybrid heating experiment, injection of power using the lowest n/sub parallel to/ antennas resulted in marked increases in plasma conductivity, hard and soft x-rays, and cyclotron radiation. The magnitudes of these increases vary inversely with n/sub e/ and n/sub parallel to/, whereas bulk electron heating was not observed at low n/sub parallel to/. These observations are interpreted as due to an RF-induced electron runaway in the DC electric field.
