Abstract
Beam dynamics and emittance growth are investigated by using particle-in-cell simulations during a final beam bunching for a driver system of inertial fusion driven by intense heavy ion beams.
Space-charge-dominated beams are transported by a transverse confinement lattice with longitudinal compression, and the emittance increases along the longitudinal beam bunching.
Dipole oscillations are excited due to the initial displacement of the beam center.
The displacement causes the additional emittance growth during the final beam bunching.
