Design and development of laser-RF Synchronization system for Thomson-scattering X-ray source at Tsinghua University

Femtosecond X-ray pulses could be generated by Thomson scattering between subpicosecond relativistic electron bunches and ultrashort infrared terawatt laser pulses. To ensure the stability and quality of the X-ray pulses, laser pulse must be synchronized to electron bunch generated by the photocathode RF gun. Here we demonstrate the design and implementation of the Laser-RF Synchronization system in Tsinghua University Thomson scatter X-ray source. Preliminary measurement shows 350 fs time jitter.
