The synchrotron radiation laboratory(SRL) is promoting advanced solid state spectroscopy using synchrotron radiation in soft X-ray and vacuum ultraviolet region. SRL operates a branch laboratory at SPring-8 to maintain the high-brilliance soft X-ray beamline BL07LSU of the University of Tokyo, where time-resolved soft X-ray spectroscopy, high-resolution soft X-ray emission spectroscopy, 3D (depth + 2D microscopy) nanoESCA, X-ray magneto-optical effect, and soft X-ray diffraction are utilized to study electronic states and dynamics in new materials. SRL developed the fast polarization switching of the undulator light source in cooperation with SPring-8. In the building E at Kashiwa campus, SRL developed the ultra-high resolution spin-resolved photoemission spectroscopy using vacuum ultraviolet and soft X-ray lasers in collaboration with laser light source scientists in ISSP.
Figure-8 undulators installed in SPring-8, which provide high-brilliance synchrotron radiation into the beamline BL07LSU.
A laser-excited spin-resolved photoemission spectrometer with VLEED spin detector, which enables us to measure spectra with very high energy and momentum resolutions.
