| Research Abstract |
It is quite important to promote experimental investigations on basic plasma phenomena, in conjunction with fusion-oriented research, space plasma phghysics,and plasma processing application. The purpose of this project is to organize experimentalists working on basic and new plasma phenomena from this point of view.
In every fiscal year, the meeting was held, together with one or two small workshops. In 1987, we had the final meeting to summarize various activities of the investigators.
We could find a lot of the results on basic and new plasma phenomena. Especially the potential formation in magnetized plasmas was well clarified, being concerned with auroral particle acceleration and plasma transport in fusion-oriented devices. In a negative ion plasma, solition and self modulation were actively investigated and, at the same time, a Q-machine plasma was used to produce a negative ion plasma with high quality. A large-diameter plasma, which is useful for plasma processing research, was successfully produced. Nonlinear phenomena, such as electron hole, ion-wave reflection, interaction of rf field with plasma, suppresion of instability, etc. were well investigated to know their new and/or detailed features. Alfven wave resonance and basic MHD self-organization behavior were also clarified.
In conclusion, a further promotion of this kind of investigation is necessary.
