ICRF (Ion Cyclotron Resonance Frequency)

Ion Cyclotron Resonance Frequency (ICRF) is the specific radiofrequency used to selectively heat charged particles (ions) in a plasma, like those in a fusion reactor. When this frequency matches the natural rotational frequency of an ion around magnetic field lines, the ions absorb energy efficiently, increasing their temperature. This process enhances plasma heating and can improve fusion conditions. ICRF is controlled carefully to target specific ions without disturbing others, making it a precise and effective method for managing plasma energy in experimental and operational fusion devices.
