Present Status of Hanbit Magnetic Mirror Device

The Hanbit magnetic mirror device, which is operated as a joint plasma research facility, has been constructed at Korea Basic Science Institute for basic study and technology development of high temperature plasma confinement, plasma heating and diagnostics, and plasma applications, such as high-temperature material testing for tokamak divertors. A 500-kW RF transmitter and a 100-kW RF transmitter for ICRF heating are major heating sources in operation, and a few gyrotron-based ECRH systems are in preparation. The target plasma parameters at the central cell are 1-keV ion temperature, 200-eV electron temperature, and 5 × 10¹² cm⁻³ electron density with 500-ms plasma duration. The present status of the Hanbit device, which includes the system overview and recent experimental result, is described in this paper, and future plans will be discussed.
