| Research Abstract |
The collective motion of an ion plasma trapped in a linear Paul trap is equivalent with that of a charged-particle beam propagating through a linear transport line. Namely, the dynamics of the space-charge-dominated beam can be studied by using the ion plasma. At Hiroshima University, a linear Paul trap system "S-POD (Simulator for Particle Orbit Dynamics)" was developed to investigate various collective effects in beams. A purpose of this theme is experimental study on evolution of a beam halo by an ion plasma confined in a linear Paul trap. It was observed that an ion plasma could produce a large halo with induced resonance instability.
