Light ion beam transport in a multi-plasma channel system

The transportation of intense light ion beams through a laser-initiated plasma channel was performed. The ion beam was generated using a pinch-reflex ion diode mounted on Reiden IV, and was propagated through the channel. Beam trajectories, estimated from the damage pattern on the cellulosenitrate film, were in good agreement with the theoretical prediction. The beam overlap in a multi-plasma channel was also studied. The triple wire-exploding channel was formed as a simulational model of overlap channel system. Post-transported beam particles in the channel overlap region were observed by a pinhole shadow box as a function of the particle energy. Beam expansion and beam deflection in the overlap region could be suppressed when channels and return paths were alternately arranged.
