| Sumario: | <p id="p1">Electrostatic ion cyclotron instability is generated when an ion beam is injected into a plasma along a magnetic field line with a multiple-mirror structure and the beam velocity satisfies a resonance condition. Under this condition, two waves with the same frequency but different wave numbers are simultaneously excited and grow in the multiple-mirror field. This phenomenon is considered parametric instability (explosive instability) caused by a stationary wave with zero frequency, that is, the periodic magnetic structure. This study was conducted by the double-plasma method using a Q-machine. The excitation characteristics of the ion cyclotron wave and the beam slow mode were clearly observed. The precise experimental results and theoretical considerations are described in this chapter.</p> |
