Perpendicular shocks are shown to be rapid particle accelerators that perform optimally when the ratio us of the shock speed to the particle speed roughly equals the ratio 1/η of the scattering rate to the gyro frequency. We use analytical methods and Monte-Carlo simulations to solve the kinetic equation that governs the anisotropy generated at these shocks, and find, for ηus ≈ 1, that the spectral index softens by unity and the acceleration time increases by a factor of two compared to the…
