Overview

This beamline, powered by the Linear Polarizing Undulator (LPU), supports in-situ soft X-ray spectroscopy and scattering experiments across 180-2500 eV with a resolution of 15000@244.4 eV and optimized photon flux. It features an SX700 monochromator with 400/800/1200 l/mm dual gratings and precision M1-M6 mirrors for beam splitting and focusing. The main line focuses at 63.5 m for the Near Ambient Pressure X-ray Photoelectron Spectroscopy (NAPA) endstation, while the branch line focuses at 69.0 m for the in-situ photon-in photon-out spectroscopy (MARS) endstation, both utilizing a 1° grazing incidence design. Enhanced by water cooling and radiation protection, the system ensures high resolution, high flux, and reliable performance for both stations.
