On September 20, the Hefei Advanced Light Facility (HALF) in China’s Anhui province successfully fired its first electron beam. This milestone was achieved using a sophisticated electron gun, which propelled electron bunches through a 192-meter linear accelerator to reach an energy level of 2.2 billion electron volts. The facility is designed to function as a 'super microscope,' a tool capable of observing matter at the atomic and molecular levels with unprecedented clarity.

The project is viewed by Chinese researchers as a critical piece of national infrastructure. By providing high-intensity light beams, the facility aims to facilitate breakthroughs in diverse scientific fields, ranging from the study of neurodegenerative diseases like Alzheimer’s to the development of next-generation microchips. The successful test of the electron gun confirms that the core technology required for the facility’s operation is functional.

While the project is currently in its testing phase, the successful acceleration of electrons is a necessary precursor to the facility's full operational capacity. The HALF project is part of a broader push by China to establish world-leading research facilities that can compete with international synchrotron light sources. Future phases of the project will focus on stabilizing the beam and integrating the facility’s experimental stations to begin scientific research.
