Abstract The Inner Shell Spectroscopy (ISS) beamline on the 8-ID station at the National Synchrotron Light Source II (NSLS-II), Upton, NY, USA, is a high throughput X-ray Absorption Spectroscopy beamline designed for the in situ, operando, and time-resolved material characterization using high monochromatic flux and scanning speed. This contribution discusses the technical specifications of the beamline in terms of optics, heatload management, monochromator motion control, and data acquisition and processing. We show the results of the beamline tests demonstrating the quality of the data obtainable on the instrument, possible energy scanning speeds, as well as long term beamline stability. The ability to directly control the monochromator trajectory to define the acquisition time for each spectral region is highlighted. The examples of studies performed on the beamline are presented. The paper is concluded with a brief outlook for future developments.
