[HEDS3-05] Electron Heating by Ion-Weibel Instability in the Presence of Finite Beam-Perpendicular Background Magnetic Field

We discuss the magnetic field amplification and electron heating by ion-Weibel instability. We present a novel dynamo-like amplification mechanism in the presence of a weak but finite background magnetic field. This scenario applies to high-Mach number astrophysical shocks such as supernova remnants.
