What are helicons?

What are helicons?. Helicons are partially ionized RF discharges in a magnetic field. They are basically whistler modes confined to a cylinder. They are much different than in free space; they have E-fields. OLD. NEW. Long cylinder. Permanent magnet. Helicons pose unending problems.
