Temporal synchronization systems, which measure electron beam time of arrival with respect to a laser pulse, are critical for operation of advanced laser-driven accelerators and light sources. State-of-the-art synchronization tools, relying on electronic e-beam response and photodetector laser response are limited to few GHz bandwidths in most practical configurations. This paper presents a temporal diagnostic instrumentation based upon a photoconductive THz antenna, which could offer an inexpensive and user friendly method to provide shot-to-shot relative time of arrival information with sub-picosecond accuracy. We describe the overall instrument design and proof-of-concept prototype results at the UCLA PEGASUS facility.
