Abstract

The coupling mechanism of boundary sheaths and a wave launcher immersed in a collisionless plasma is experimentally clarified by the addition of an electron emission from the launcher. The wave amplitude increases rapidly with increasing electron emission. The strong increase in a directly coupled signal is a clear observation of ion-acoustic waves which are simultaneously excited at the sheaths.
