Ion acceleration by a quasistatic field of a modulated high-current electron beam in a corrugated liner

The ion acceleration by a modulated high-current electron beam in a corrugated liner is theoretically investigated. A corrugation shape providing ion synchronism with an accelerating wave field is found. The law of accelerated ion energy variation is determined. Stability of ion radial and phase motion in the acceleration regime is studied. The maximum ion current is estimated. Requirements to the basic accelerator parameter tolerances are found. The amplitude of accelerating wave electric field in the acceleration scheme under consideration is a small (∼ 10%) part of the static electric field. The conclusions are made that at electron beam current < or approx. 10 kA and beam radius > or approx. 0.5 cm the rate of proton accelration does not exceed 5 MeV/m. The rate of ion acceleration is proportional to the electron beam current its modulation factor and ion charge degree and inversely proportional to the beam radius. The optimal accelerating section length is 1-2 m
