Breaking Barriers: World’s First Dual-Beamline Photoelectron Momentum Microscope Unveiled in Japan

Credit: Prof. Fumihiko Matsui Group, Institute for Molecular ScienceJapans UVSOR Facility reveals the first dual-beamline photoelectron momentum microscopic lense, improving the research study of electron habits in materials and advancing materials science.The worlds very first dual-beamline photoelectron momentum microscopic lense has actually been developed at the UVSOR Synchrotron Facility, Japan. By branching the existing vacuum ultraviolet (VUV) beamline BL7U, VUV light has actually now ended up being at the same time readily available at the photoelectron momentum microscopic lense in addition to a soft-X ray beam from the beamline BL6U.This worlds first “dual-beamline photoelectron momentum microscopic lense” allows 1) element-selective measurements using the grazing-incidence soft X-ray light and 2) highly symmetric measurements utilizing the normal-incidence VUV light. In this work, we applied this method to the valence electrons of the Au( 111) surface.This unique dual-beamline photoelectron momentum microscopy uses deeper insights into the behavior of electrons in materials, innovating fields of condensed matter physics, molecular science, and products science.Reference: “Development of dual-beamline photoelectron momentum microscopy for valence orbital analysis” by Kenta Hagiwara, Eiken Nakamura, Seiji Makita, Shigemasa Suga, Shin-ichiro Tanaka, Satoshi Keraa and Fumihiko Matsui, May 2024, Journal of Synchrotron Radiation.DOI: 10.1107/ S1600577524002406The research study was funded by the MEXT Fostering Joint International Research (B), and a MEXT Grant-in-Aid for Scientific Research(S).
