Description
In order to achieve high energy resolution in nuclear physics experiments, it is important to maintain the beam quality during beam transport from the injector to the accelerator and to the experimental instruments. At the Research Center for Nuclear Physics (RCNP), the University of Osaka, high-resolution beams are currently obtained by injecting beams from an ECR ion source into the accelerator and collimating them with slits throughout the acceleration. However, this method leads to increase losses of beam intensity and a beam halo, so it is desired to generate high-quality beams directly at the ion source without collimations.
As a solution to the issues, we are developing the LaPRIS (Laser Plasma RF Ion Source) method. LaPRIS is a pulsed ion source that generates and extracts slow ions by combining a gas jet, an RF field and ultra short pulse laser. In this method, the ions are extracted from plasma generated at the laser focal spot by RF field. They form a short-pulsed bunch with a small spatial and time profile.
In this paper, we will discuss preliminary results obtained by generating laser-induced plasma through focused laser in a jet of thin gas and measuring the generated ions.
