Research Abstract

A table top electrostatic ion storage ring with the circumference of 0.8 m was designed and built. The design concept of the ring is not only miniaturization but also transportable for various research facilities outside of the university. Stability of ion trajectories in the ring was considered by ion optical simulations by referring from the electrostatic storage ring with ten times in size equipped at Tokyo metropolitan university. Then the tabletop electrostatic ion storage ring and its electric power supply and particle detector have been developed with taking care of accuracies of machining and assemblage due to the miniaturization.
