The Spectroscopy and Coherent Scattering (SCS) Instrument provides time-resolved X-ray spectroscopy tools to investigate the electronic structure of complex materials and reveal material dynamics on nanometer length scales using soft X-rays. This document reports on the scientific outcome from the first three years of SCS operation. To provide the full scope of instrumentation capabilities, it further includes recent preliminary results from the user-assisted commissioning of the RIXS spectrometer and CHEM station. In terms of instrument operation, beam stability, special operation modes, the use of detectors, and online and offline data analysis are further described. Supported by the in-house R&D programmes, further short- and mid-term instrumentation upgrades are listed at the end of this report. These include tunable THz sources, novel timing diagnostics, and new X-ray methodologies and experiment station upgrades.
