Every powerful X-ray pulse produced for experiments at a next-generation laser project, now under construction, will start with a "spark" – a burst of electrons emitted when a pulse of ultraviolet ...
In the ionization injection regime of laser wakefield acceleration (LWFA), the control and optimization of electron bunches is a major concern. We address this by demonstrating the generation of ...
Laser wakefield acceleration (LWFA) is a promising method to realize compact high-energy electron accelerators because of its significant acceleration field beyond 1 GV/cm 1. In the past decade, LWFA ...
