Title:	Beam Dynamics Studies in High-flux Ion Injectors and during Longitudinal Bunch Compression for High Power Ion Acceleration
Abstract:	We discuss the beam dynamics in high-flux ion injectors and also in a transport line for longitudinal bunch compression. Two schemes of high flux ion injectors from moving plasma are comparatively discussed; one is ion extraction from a laser-produced expanding plasma and another is from a dense, compressing plasma. A laser-ablation plasma source was evaluated for low emittance and/or high flux ion beams. The expanding (cooling) plasma was restricted within narrow radial area by an axial magnetic field, which potentially allows us to extract low emittance beams. A dense, drifting plasma from pinched discharge in a tapered capillary was also tested for extremely high current ion sources. A fast pulsed discharge in the capillary compresses and accelerates the pinching plasma, which enables us to extract high flux ion beams. Although a longitudinal bunch compression is essential for generation of energetic particle beams, it inevitably accompanied by emittance growth due to a non-linear fluctuation in the beam transport line. We constructed a small electron accelerator, composed of an induction modulator and a solenoidal transport line, to discuss evolutions of the beam bunch and the beam emittance during the longitudinal compression.
