Abstract
A quasi-equilibrium and recirculating compression scheme has been suggested for the beam bunching of heavy ion fusion. The recirculating beam buncher consists of induction linacs and bending sections. Induction modulators apply the velocity tilt for beam compression. The applied voltage is controlled so as to moderate the velocity tilt by the space charge force before the bending sections. As a result, the repulsion force of the beam is generally balanced with the bunching force during the compression process. Consequently, while the beam is gradually compressed under a quasi-equilibrium condition, the transverse mismatch from the velocity tilt of the bunching beam is suppressed to an allowable level.
