- 論文の詳細を見る
The current neutralization fraction of Rotating LIB injected into a low density plasma (about 1 Torr) is investigated numerically. The beam space charge is easy to be almost neutralized by a redistribution of the background plasma. But if the Larmor radius of the plasma electron is much smaller than electron-ion collision mean-free-path, the return current induced in the plasma is limited to flow by the strong magnetic field associated with the intense LIB. Consequently the beam current cannot be neutralized so much. In this reserch, the macroscopic treatment of such a phenomenon is presented and the possibility of Rotating LIB propagation is also considered.
