Abstract
The results of a theoretical study of dual-beam charged-particle acceleration in a plasma waveguide in a string longitudinal magnetic field are presented. It is shown that effective charged-particle acceleration can be realized by using electric-field nonuniformity over the waveguide cross section. It is established that optimal acceleration conditions can be achieved when the particles enter the accelerating field that corresponds to the region of the first amplitude maximu. The maximum electron energy of the accelerated beam is determined as a function of the guiding-beam current. It is established that the current of accelerated electrons that have maximal energy is 5–10% of the total beam current.
