Recent advancements in materials science increasingly rely on high-brightness synchrotron X-rays to uncover the structural, electronic, and chemical properties of advanced materials at the atomic-scale. Korea-4GSR, a 4th-generation synchrotron facility currently under construction, introduces four specialized beamlines tailored for materials research: Real-Time XAFS (X-ray Absorption Fine Structure), MSA (Material Structure Analysis), Soft X-ray Nanoprobe, and NanoARPES. Each beamline is optimized for core techniques such as X-ray absorption spectroscopy, high-resolution powder diffraction (HRPD), X-ray photoelectron spectroscopy (XPS/AP-XPS), and angle-resolved photoemission spectroscopy (ARPES), offering unparalleled precision and speed. The Real-Time XAFS beamline enables sub-second XAFS and XES measurements under dynamic in-situ/operando conditions. The MSA beamline delivers high-resolution, rapid powder diffraction analysis tailored for industrial applications. The Soft X-ray Nanoprobe beamline provides flexible configurations for high-throughput XPS/XAS analysis across 0.1‒5 keV, including ambient pressure XPS. The NanoARPES (Nanoscale Angle-resolved Photoemission Spectroscopy) beamline, the first dedicated nanoscale ARPES facility in Korea, delivers high spatial and momentum resolution for probing localized electronic structures in quantum and 2D materials. Together, these beamlines form a next-generation analytical platform, enabling real-time, atomic-scale investigations that will drive innovation across semiconductors, energy materials, and catalysis.
