Abstract:Laser-plasma electron accelerators can be used to produce high-intensity X-rays, as electrons accelerated in wakefields emit radiation due to betatron oscillations. Such X-ray sources inherit the features of the electron beam; subfemtosecond electron bunches produce betatron sources of the same duration, which in turn allow probing matter on ultrashort time scales. In this paper we show, via Particlein-Cell simulations, that attosecond electron bunches can be obtained using low-energy, ultra-short laser beams … Show more
