| Abstract | A system to generate ultra-slow beams of highly ionized ions (HICIs) is under construction at RIKEN for studying collision processes of slow HCis with atoms, molecules and surfaces. HCIs beams produced with an ECR ion source are transported to a multi-electrode trap, which can include several local harmonic potential wells enabling to confine different nonneutral plasmas of oppositely charged particles. Injected HCIs are decelerated by a dense electron plasma and then, to evade their recombination with electrons, cooled further with a positron plasma under cyclotron radiation cooling. This electron plasma also works as the damper of slow positrons at their loading into the trap. The cold HCis are finally extracted from the trap as an ultra-slow beam with well-defined energy and used for slow collision experiments. |
