A novel internal target has been developed, which will make electron scattering off short-lived radioactive nuclei possible in an electron storage ring. An "ion trapping" phenomenon in the electron storage ring was successfully utilized for the first time to form the target for electron scattering. Approximately 7×106 stable Cs133 ions were trapped along the electron beam axis for 85ms at an electron beam current of 80mA. The collision luminosity between the stored electrons and trapped Cs ions was determined to be 2.4(8)×1025cm-2s-1 by measuring elastically scattered electrons.
