Abstract  Inner belt energetic protons are a hindrance to development of space technologies. The emission of electromagnetic ion cyclotron (EMIC) waves from spaceborne transmitters has been proposed as a way to solve this problem. The interaction between particles and narrowband emissions has been typically studied using nonlinear test particle simulations. We show that this formulation results in a random walk of the inner belt protons in velocity space. In this paper we compute bounceaveraged pitch angle diffusion rates from test particle simulations and compare them to those of quasilinear theory for quasimonochromatic EMIC waves interacting with inner belt protons. We find that the quasilinear solution is not sensitive to the frequency bandwidth for narrow distributions. Bounceaveraged diffusion coefficients from both approaches are in good agreement for all energies and pitch angles. The interaction with inner belt protons, therefore, can be addressed using quasilinear diffusion codes, which allows faster exploration of parameter space.
