3He and heavy ion enrichment in solar energetic particles as evidence
for cyclotron resonances with linear waves
Abstract
In this talk, I will draw distinction between linear plasma waves and
strong turbulent fluctuations and argue general characteristics of 3He
rich solar energetic particle events favor the scenario that 3He ions
are mostly energized via cyclotron resonance with proton cyclotron
waves. These waves can be produced via magnetic reconnection at the ion
diffusion scale and/or via cascade of turbulence energy from low to high
frequencies. Both PIC and hybrid simulations can be used to verify these
scenarios.
