New schemes for enhancing hard X-ray emission with laser plasma accelerators

全体主题 > 极端条件下的物理学

Laser Plasma Accelerators (LPA) rely on our ability to control the electrons motion with intense laser pulses. The manipulation of such relativistic electrons allows a fine mapping of the longitudinal and radial components of giant electric fields with values that can exceed hundreds of GV/m [1]. This control is crucial to optimize the design of laser plasma accelerators for delivering ultra-short and ultra-bright energetic particle or radiation beams. To illustrate the beauty of laser plasma accelerators I will show some concepts that give improvements the quality of the electron beam, its stability [2] and its energy gain [3], and its divergence [4].
I’ll then show how by controlling the quiver motion of relativistic electrons intense and bright X-rays beam are produced in a compact and elegant way [5-7]. Finally I’ll show some new ideas [8,9] for producing intense Gamma rays beam of relevance for nuclear applications.
