Generation of Mesoscale Magnetic Fields and the Dynamics of Cosmic Ray Acceleration
P. H. Diamond, M. A. Malkov
The problem of the cosmic ray origin is discussed in connection with their acceleration in supernova remnant shocks. The diffusive shock acceleration mechanism is reviewed and its…

Intrinsic energy cut-off in diffusive shock acceleration: possible reason for non-detection of TeV-protons in SNRs
M. A. Malkov, P. H. Diamond, T. W. Jones
The linear theory of shock acceleration predicts the maximum particle energy to be limited only by the acceleration time and the size of the shock. We study the combined effect of…

Asymptotic Theory of Particle Trapping in Coherent Nonlinear Alfven Waves
M. V. Medvedev, P. H. Diamond, M. N. Rosenbluth +1
A fully nonlinear, time-asymptotic theory of resonant particle trapping in large-amplitude quasi-parallel Alfven waves is presented. The effect of trapped particles on the nonlinea…
