Helicon discharge

Helicon discharge is a type of plasma generation that uses specific electromagnetic waves, called helicon waves, to efficiently ionize gases. These waves are launched into a low-pressure gas environment, causing the gas molecules to become charged and form plasma—a highly conductive state of matter. Helicon discharges typically produce dense, uniform plasma at relatively low power levels, making them useful in applications like semiconductor manufacturing, space propulsion, and materials processing. The process relies on the resonance of the helicon waves with the magnetic field to enhance the ionization efficiency, resulting in a stable and controllable plasma source.
