Measurement of laser-accelerated electron beam emittance and source size

This paper experimentally demonstrates a new laser-based method for measuring important properties of laser-accelerated electron beams, including their emittance and source size. The method works by using an optical interference pattern to modulate the electron beam's phase space. Results match previous measurements, and calculations show the method is robust to noise and uncertainty.
