RF POWER AND MAGNETIC FIELD MODULATION EXPERIMENTS WITH SIMPLE MIRROR GEOMETRY IN THE CENTRAL CELL OF HANBIT DEVICE

摘要

The radio frequency (RF) stabilization effects to investigate the characteristics of the interchange instability by RF power and magnetic field modulation experiments were performed near ω/Ω_i ≈ 1 and with low beta (～0.1%) plasmas in the central cell of the Hanbit mirror device. Temporal behaviors of the interchange mode were measured and analyzed when the interchange mode was triggered by sudden changes of the RF power and magnetic field intensity.
