The chemRIXS instrument at the Linac Coherent Light Source (LCLS) offers new opportunities for studying solution-phase systems with time-resolved soft x-ray spectroscopic methods such as resonant inelastic x-ray scattering (RIXS) using the recently commissioned high-repetition-rate LCLS-II x-ray free-electron laser. The orders-of-magnitude x-ray flux improvement provided by the superconducting accelerator, combined with corresponding advances in the optical laser system and the liquid-jet recirculation system, enables studies on dilute systems with high signal-to-noise compared to what was possible with the LCLS-I copper accelerator. These capabilities open up time-resolved x-ray absorption spectroscopy and RIXS to entirely new classes of samples, as well as enable the development of new soft x-ray spectroscopic methods on liquid samples. An overview of the beamline components and the first LCLS-II commissioning results is presented.
