Japan Synchrotron Radiation Research Institute (JASRI), Tohoku University, and Japan Atomic Energy Agency has achieved imaging of the electron state of cuprate high-temperature superconductor which results in its high-temperature superconductivity, using high-intensity and high-energy X-ray by Super Photon ring-8GeV (Spring-8), the large radiation facility, at the first time in the world. This achievement will serves as a stepping stone to elucidation of the high-temperature supercondution mechanism, which is essential for the material design of room temperature superconductor. 　

 This achievement has been produced through a joint research by Associate Senior Researcher Yoshiharu Sakurai and Associate Senior Researcher Masayoshi Ito at JASRI, Professor Kazuyoshi Yamada and Assistant Professor Masaki Fujita at Tohoku University, Associate Senior Researcher Shuichi Wakimoto at Japan Atomic Energy Agency, and 4 foreign universities including Northeastern University and École Centrale Paris. This research result was published online in Science Express on April 28, 2011. The paper's title is "Imaging Doped Holes in a Cuprate Superconductor with High-Resolution Compton Scattering".
