Ball plasma dynamics for FBX BURNER reactor

Summary form only given, as follows. We have conducted fundamental experiments on moving plasma balls in the major axis direction. This has a fundamental importance for the quasi-steady fusion reactor scheme with the moving flowing fuel type fusion reactor FBX BURNER. This configuration is the descendants of Spheromak type nuclear fusion scheme but with a long toroidal field coils. The main issues have been focused onto the dynamic stability of the moving plasma balls. The second issue is the collision between two successive plasma balls. This shows a basic result from an optical measurement. The comparison with magnetic measurements shows peculiar but interesting features of the system. The dimension of our plasma injector is 2 m in length. It has a coaxial configuration. The external electrode is 150 mm in inner diameter and the inner electrode is 50 mm in diameter. This is attached to a 1 m insulation reservoir with the same inner diameter. An axial magnetic field up to 0.1 Tesla is applied to the discharge with a current of up to 10 kA in few ms.
