Fluctuations in few-electron pulses between the quantum limit and space-charge regime (A04)

Subject Area Optics, Quantum Optics and Physics of Atoms, Molecules and Plasmas
Nuclear and Elementary Particle Physics, Quantum Mechanics, Relativity, Fields
Term since 2021
Project identifier Deutsche Forschungsgemeinschaft (DFG) - Project number 425217212
 
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 the level of the individual particles and their trajectories in space and time.
