Abstract
The first plasma experiment using the Ring Trap-1 (RT-1) was performed on January 12, 2006. The RT-1 is a novel plasma device constructed to explore ways to the advanced-fuel fusion. The mechanism of plasma confinement is based on the theory of high-beta equilibrium that is self-organized in a flowing plasma. A superconducting ring, levitated in the vacuum chamber, produces a magnetic field that traps high-temperature plasma, creating a magnetosphere-like configuration. Plasma is produced by electron cyclotron heating using an 8.2 GHz microwave.
Keywords
flowing plasma, high-beta plasma, double beltrami field, high Tc superconductor

Movie
The first plasma experiment performed on the RT-1 device. The plasma is produced by ECH using an 8.2 GHz microwave. The pulse duration was 1 sec, as determined by the microwave operation. In the second video, the ring magnet was levitated about 30 mm over the lifter, while in the first video it was placed on the lifter.
