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.

设计并制作了周长为0.8 m的台式静电离子储存环。该环的设计理念不仅是小型化，而且可以运输到大学以外的各种研究设施。参考东京都立大学配备的十倍大小的静电存储环，通过离子光学模拟考虑了环中离子轨迹的稳定性。然后开发了桌面静电离子存储环及其电源和粒子检测器，并考虑到小型化的加工和组装精度。
