It is experimentally shown that ion heating occurs because of ion acoustic waves arising from the drift of electrons in an ion-streaming plasma. The drift of electrons is controlled by changing the bias applied to a meshed grid inserted in the plasma. The results of this work indicate that, when the drift velocity of electrons is settled at a proper value, one can observe standing-wavelike ion acoustic waves as well as the increase of ion-temperature, and that there is a good correlation between the increase of ion-temperature and the amplitudes of the ion-waves. Explanation of the mechanism of ion heating is also described.
