Abstract

Radio frequency magnetoplasmic waves know as helicons will propagate in solid – state plasmas of metals and semiconductors when a strong magnetic field is applied. In Helicon Maser the helicons are excited by RFs much higher than the Helicon generation frequency. The bandwidth of HM is much narrower than in case of isolated sample resonator (the same situation as in laser). InSb was used for active material in the experimental device. The constant magnetic field varied within the interval 0 – 20 Tesla. The equivalent circuit of the HM is considered. The experiments were performed at the Grenoble High Magnetic Field Laboratory (France) through the EEC "Access to Research Infrastructure action" Program.
