We are pleased to announce the first workshop on Frontiers in Ultrafast Scattering of Electrons (FUSE), to be held August 27-29, 2025 at SLAC National Accelerator Laboratory in Menlo Park, California. The workshop aims to enhance the visibility of relativistic electron scattering as a critical research tool, foster collaboration across the broader ultrafast electron diffraction (UED) community (including both relativistic and nonrelativistic UED instruments), and serve as a platform for practitioners to exchange ideas, share breakthroughs, and address emerging challenges. The workshop is open to the global UED science and instrument development community to attend. We will arrange invited talks from international leaders, particularly those from regions with significant UED investments, to relate recent scientific developments, share capabilities and progress from emerging UED facilities, and identify opportunities for innovation. An auxilliary goal is to inform SLAC’s MeV-UED program so that it will remain user-driven while adapting to evolving trends in ultrafast science. Such engagement will be vital for maintaining the value of MeV-UED as a research tool and maximizing its scientific impact.
