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.

氘-3融合的背面实现需要高于50％的高β等离子体构型的发展，含量为Tokamak（如Tokamak）的含量为tokamakss.s.objective，需要对现场转换式配置（FRC）等离子体（FRC）等离子体已可以接受，该值是90％的Beta值。 FRC研究中最关键的问题之一是发现了维持FRC等离子体的溃败。出于目的，研究限制的特征和改进，并开发中性束注入和磁压缩的方法。归因1。许多仪器已深入研究了粒子限制时间，并发现为0.3ms。同样，随着镜像比率的增加，可以延长时间。 2。在磁压缩实验中； 80％的轴向压缩为融合芯提供了更多的脂肪frc Supeabe，并延长了禁闭时间的延长。 3。通过开发具有IGBT控制的新功率超级，已经安装了500kW类的高功率束喷射器。现在，正在以低水平的功率获得有关注射的物理数据，以开发一些新的粒子探测器。
