38. The Theory of SEP Acceleration and Transport

Prof. Martin Lee (University of New Hampshire)

Solar energetic particles (SEPs) are a major constituent of the inner heliosphere during “Solar Maximum” conditions. SEPs occur in two basic classes of events. “Gradual” events are large, infrequent, last for days, are proton-rich, and are associated with coronal mass ejections (CMEs) and type II radio bursts. “Impulsive” events are small, frequent, last for hours, are electron-rich, and are...

29. Kinetic simulations of particle acceleration at collisionless shocks

Damiano Caprioli (Princeton University)

I present some recent results of large particle-in-cell (PIC) and hybrid (kinetic ions-fluid electrons) simulations of particle acceleration at non-relativistic collisionless shocks. Ion acceleration efficiency and magnetic field amplification are investigated in detail as a function of shock inclination and strength, and compared with predictions of diffusive shock acceleration theory. In...
