Plasma-based spatiotemporal synchronization and alignment of electron and laser beams

Activity: Talk or presentation typesOral presentation


Advanced particle accelerators and their applications rely on exact synchronization and alignment of laser pulses with respect to charged particle beams. Prominent examples are pump-probe experiments with free electron lasers and plasma photocathode accelerators..
The presentation discusses a novel technique which harnesses enhanced plasma recombination glow from impact ionization from laser-triggered plasma sparks. Spatial as well as temporal transitions triggered by this interaction allow for synchronization and alignment of ultrashort electron beams and laser pulses with few or even sub-fs accuracy and µm-level spatial sensitivity. This system was developed as integral diagnostics for the E210 campaign at FACET via a simple and robust layout, which may find application in a wide range of conventional as well as plasma-based accelerator setups.
