About

Harold Barnard is a leading figure in the development of advanced X-ray scattering instrumentation, with a primary focus on high-throughput, automated characterization of thin-film materials. His most notable contribution is the creation of a robotic grazing-incidence wide-angle X-ray scattering (GIWAXS) platform at the Advanced Light Source’s SAXS/WAXS beamline, which integrates a UR5e robotic arm, a helium-purged sample chamber, and custom data acquisition routines. This system dramatically accelerates the structural analysis of organic electronics and photovoltaic materials, enabling researchers to screen hundreds of samples per day with unprecedented precision and reproducibility. Though his seminal 2025 paper on the topic currently holds 3 citations, its impact is expected to grow as the platform becomes a standard tool for high-throughput materials discovery. Barnard’s work bridges the gap between synchrotron science and industrial-scale characterization, making him a key enabler of next-generation energy and electronic devices. His contributions exemplify how automation and robotics are transforming beamline science, offering students and researchers a powerful new avenue for rapid, data-rich experimentation.
