Electron beams and short electron pulses are central to a wide range of modern research and technology, but they suffer from space charge effects due to statistical electron-electron interactions. Here we combine laser-triggered few-electron emitters with a femtosecond single-electron detector at close to 100% quantum efficiency and aim for detecting the fundamental origin of beam fluctuations on level of the individual particles and their trajectories in space and time.
