During the past few decades, resonant Auger spectroscopy (RAS) has presented some
advantages in elucidating the electronic structure of free molecules, liquids, and solids. To
further extend the application of RAS in complex in situ environments, the ambient pressure
system should be developed to characterize the gas–solid and liquid–solid interfaces. In this
paper, we describe the design and performance of an ambient pressure mapping of
resonant Auger spectroscopy (mRAS) system newly developed at BL02B01 at the Shanghai …
