(Top) Schematic of an EPU beamline (10A) for STXM at the Pohang Light Source. Front-end (FE) and photon transfer line (PTL) slits are used to allow only the useful portion of X-rays to pass through. (Bottom left) Measured photon flux as a function of photon energy with 400 and 1000 lines mm−1 gratings. First-order and third-order harmonics are plotted. (Bottom right) N K-edge absorption spectrum obtained from molecular nitrogen: the spectral features of vibrational modes indicate that the spectral resolving power (E/ΔE) of the beamline is ∼5000. The deconvoluted spectral lines are shown. |
