Effects of stationary electrons on the Buneman instability in a bounded electron beam-plasma system are investigated theoretically and experimentally. The Buneman instability is generated in a low-beam-current regime and is coupled with the Pierce instability in the high-beam-current regime. The threshold current of the Buneman instability is considerably increased by introducing a small amount of stationary electrons into the system.
