| Research Abstract |
We have experimentally studied the space-charge effects that might seriously affect the stability of high-quality hadron beams in next-generation particle accelerators. For this purpose, very compact and low-cost non-neutral plasma traps were developed which generate, in the laboratory frame, many-body systems physically equivalent to relativistic charged-particle beams. Employing this novel experimental method, we systematically explored nonlinear collective phenomena caused by interparticle Coulomb interactions and obtained useful quantitative information to improve the stability of high-quality beams.
