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.
