Abstract :
A novel high-gradient magnetic field-decay accelerator is presented in which the drive-beam leaves behind a high-gradient accelerating field produced by the magnetic field decay. The electromagnetic fields indicate a decaying function of the time. As an example, we obtain the acceleration field for the case of a short and intense drive bunch, which is represented by a parabolic function of time. With appropriate physical parameters, the acceleration gradient of the magnetic field-decay accelerator can be easily more than 150 megavolt/meter
