摘要：
The evolution of the self-generated magnetic fields during the transportation of inhomogeneous fast electron beams with Gaussian and super-Gaussian density profiles in cylindrical specially engineered targets is studied. The analysis is based on a fluid model for electron beam, and we consider the low-density core with a high-density cladding structure for cylindrical targets. Gaussian and super-Gaussian density distributions of the electron beam generate the spatial extent of magnetic fields, while their magnitude decreases greatly at the boundaries, compared to the homogeneous distributions.
