About

R. den Hartog is a leading figure in the development of advanced X-ray optics, with a primary focus on Silicon Pore Optics (SPO) technology. Their major contribution lies in pioneering a method to construct lightweight, high-resolution X-ray mirror modules using silicon plates and semiconductor fabrication techniques, combined with custom robotic assembly. This innovation solves the critical challenge of aperture segmentation, enabling the creation of large, powerful X-ray telescopes that would otherwise be prohibitively heavy. Den Hartog’s 2023 paper, "Silicon pore optics: a mature and adaptable x-ray mirror technology," with 4 citations, serves as a definitive reference for the field, demonstrating the technology’s readiness for flagship missions. This work is foundational for next-generation observatories like ESA’s Athena, where SPO is the baseline technology. By adapting industrial processes from microelectronics, den Hartog has not only advanced space science but also opened new pathways for cost-effective, scalable X-ray optics, cementing their reputation as a key innovator in astronomical instrumentation.
