Abstract :
A novel high-gradient wakefield accelerator is presented in which the drive-beam current leaves behind a high-gradient wakefield, accelerating the witness beam to very high energy. The theoretical analysis is based on Faraday´s law, which provides a second-order partial-differential equation of the azimuthal magnetic field, under the assumption that με≫1. The accelerating field can be more than one half of one gigavolt/meter in an appropriate choice of system parameters
