| 内容記述 | Reflection of the ion-acoustic wave from the ion sheath in front of the separation grid in a double plasma device was investigated experimentally. The plasma potential Φ of the source plasma was controlled against the target plasma. When eΦ<-κT_e, where T_e is the electron temperature, no reflection was observed. the reason of this is that ions are drifting toward the grid with the Bohm velocity, i.e., the ion-acoustic velocity. When eΦ>κT_e, the reflected wave consists of the ion-acoustic wave and ion beam mode. The reflection coefficient for the ion-acoustic wave is about unity. This high efficiency is due to reflection of ions themselves. | |||||||||
