Proof-of-principle experiments on the induction synchrotron concept are scheduled using the KEK 12-GeV proton synchrotron, in which rf bunches and a superbunch will be accelerated with a long step voltage generated in the induction accelerating gaps.

In order to investigate the beam dynamics during longitudinal compression in high power ion accelerator, we constructed a compact bunching simulator device based on electron beams with an induction voltage adder configuration. The compression ratio a

We investigated the interaction of a laser ablation plasma with a longitudinal magnetic field aiming to create a directionally moving plasma for high-flux and low-emittance ion injectors. To study the plasma dynamics, time-of-flight measurements and

We propose a new type of plasma source with a tapered pinch discharge to form dense, high-speed plasmas. Parameters controlling the behavior are indicated by considering the pinching dynamics of current sheet based on a 1-D equation of motion. The ba

A quasi-statically tamped target for warm dense matter (WDM) experiments using all-ion accelerator (AIA) is presented. We compare the target state and homogeneity based on the KEK AIA with and without injector. For making WDM based on KEK AIA (withou

Dynamics of high-current heavy-ion beams are studied during longitudinal bunch compression. Operation regions of particle beams are plotted on a tune depression–wave velocity diagram. Emittance growth due to the transverse focusing field error is i
