China's HALF facility fires first electron beam, advancing super microscope project

China's Hefei Advanced Light Facility (HALF) in Anhui province successfully fired its first electron beam on September 20, accelerating electrons to 2.2 GeV via a 192-meter linear accelerator. This milestone moves the project closer to building a fourth-generation synchrotron light source, which could enable breakthroughs in materials science, biology, and chip manufacturing. The achievement signals China's growing capability in advanced scientific infrastructure, though full operational status and research output remain years away.
