Self-Confining Radioactive Ion Target (SCRIT) for Electron Scattering off Unstable Nuclei

Abstract

We are now developing a novel internal target system, which is to be used in an electron storage ring. This is named SCRIT (Self-Confining Radioactive Ion Target). This technology can localize specific ions on the electron beam axis using so-called “ion-trapping” phenomenon and form a fixed target of unstable nuclei. This will realize electron-scattering experiments for short-lived nuclei that have never been succeeded in. The R&D study of the SCRIT is now under way at the KSR in Kyoto University. We confirmed that ¹³³Cs ions, which were injected from outside, were trapped in the SCRIT. The SCRIT technology will open a new application of electron rings.
