Development of a tabletop electrostatic ion storage ring for macromolecular science

设计并建造了周长为0.8m的台式静电离子储存环。环的设计概念不仅是小型化，而且还可以运输到大学以外的各种研究设施。参考东京首都大学装备的10倍大小的静电储存环，通过离子光学模拟研究了环中离子轨道的稳定性。在此基础上，研制了台式静电离子储存环及其电源和粒子探测器，并考虑了小型化带来的加工和装配精度问题。

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.
