The history and development over more than 25 years is presented and discussed of an ultra-small-angle X-ray scattering (USAXS) instrument dedicated to serving a broad range of materials research needs. This history is traced from the instruments origins as a collaborative development project between the National Institute of Standards and Technology (NIST) and Northwestern University, through its initial development and application at the National Synchrotron Light Source (NSLS), Brookhaven National Laboratory, and its transfer from NSLS to the Advanced Photon Source (APS), Argonne National Laboratory. The USAXS instruments subsequent development and application at the APS in collaboration with NIST is described, and the recent, ongoing, major enhancements of the instrument at APS, in collaboration with both NIST and the University of Chicagos Chemistry and Materials Center for Advanced Radiation Science (ChemMatCARS), are discussed. The progressive improvements in hardware and software, and in general instrument performance and capability, are quantitatively detailed, and examples provided that exploit these improvements.
