Abstract
A new amplification mechanism for self-induced magnetic fields and the associated filamentation of hot-electron flow by these magnetic fields are demonstrated. The amplification mechanism is due to a spatially nonuniform convection and a consequent piling up of the magnetic field, related to hot-electron energy deposition. Two-dimensional simulations, showing the space-time evolution of magnetic field fluctuations, and a theoretical interpretation are provided.Keywords
