Abstract

Abstract: The generation of relativistic electron beams in hollow glass capillaries is investigated using a picosecond laser system. A plasma is formed in a capillary due to the ablation of its inner walls by a specially formed pre-pulse. Electron beams with an opening angle of ≈40 mrad, exponential energy spectrum with maximum energy about 20 MeV, and a total charge of ≈0.2 nC are experimentally detected.
