| Research Abstract |
Back ground Realization of deuterium-helium-3 fusion requires the development of high-beta plasma configuration above 50%, insead of low-beata toroids like as tokamaks.
Objective For the requirement a field-reversed-configuration (FRC) plasma has been acceptable, which has the beta value of 90%. One of the most crucial problems in FRC study is to found the rout to the sustainment of the FRC plasma. It is, for the purpose, to study the characteristics and the improvement of the confinement, and to develop the methods of neutral beam injection and magnetic compression.
Results 1. The particle confinement time has been intensively studied by many instruments, and is found to be 0.3ms. Also, the time could be extended with increasing of the mirror ratio. 2. In the magnetic compression experiment ; 80% axial compression has offered the more fat FRC shape suitabe for the fusion core, and exibites the extention of confinement time. 3. By development of a new power suplier with IGBT control, a high power beam injector of 500KW class has been installed. Physics data on the injection are now being obtained in a low level power, where it is needed to develop some new particle detector.
