The Oxford Atomic and Laser Physics webinar series welcomes Dr Jessica Shaw (Rochester University).

Laser wakefield acceleration (LWFA) is a method of accelerating electron beams to relativistic energies using intense lasers to drive waves in plasmas. The accelerating gradients in plasmas are three orders of magnitude higher than in conventional radiofrequency particle accelerators, making LWFA a path to compact sources of MeV-GeV electrons for potential uses in particle colliders and x-ray sources. This talk will present on the latest development in LWFA at the University of Rochester’s Laboratory for Laser Energetics. We have recently demonstrated record-breaking electron beam charge with the acceleration of 700 nC electron beam from a self-modulated laser wakefield accelerator driven by the OMEGA EP laser. Our new “flying focus” concept, a method of spatiotemporally controlling laser propagation, shows promise as a means to circumvent the fundamental limitations of LWFA and offers a path to a single-stage 500 GeV laser wakefield accelerator.
