Particle acceleration by inverse-weibel instability

A high demagnetization rate ∂B/∂t can be obtained through fast decoupling of a magnetic field from an electric circuit which generates the magnetic field. Nowadays fast decoupling is possible by present switching technologies. A high particle-acceleration gradient can be obtained in an inductive acceleration system compared with that in a conventional induction accelerator. Based on this new proposal, inductive ion and electron accelerations are investigated numerically. The mechanism presented in this paper may be considered as pseudo-inverse Weibel instability.
