摘要：

The generation of surface waves due to a strong gradient in the plasma density and its coupling to kinetic Alfven waves near the Io plasma torus are found to be a viable mechanism for particle acceleration leading to a beam of energetic electrons along the magnetic field. It is shown that acceleration to a few kiloelectronvolts is possible and this might explain the intense auroral hiss observed near the inner edge of the Io plasma torus by Voyager 1.
