AB: The only natural masers that can be studied experimentally in-situ are magnetospheric masers. Concept of the magnetospheric cyclotron maser has been derived from the self-consistent theory of the radiation belts. In this natural maser energetic charged particles serve as an active substance, and an electro-dynamic system is formed by the magnetic flux tube filled with the background plasma and corresponding ionospheric footprint. The forthcoming RESONANCE project will provide the opportunity for multipoint measurements of waves and plasma processes involved in magnetospheric masers phenomenon. It will allow detailed in-situ studies of resonant wave-particle interactions that excite pearl and whistler waves in the inner magnetosphere. Methods of linear and nonlinear processes identification that quantify the dynamics of plasma waves generated by magnetopsheric masers are considered. The proposed technique allows differentiating between the linear wave-particle interaction and nonlinear processes of energy transfer in plasma turbulence.
