Fast electron beam with manageable spotsize from laser interaction with the tailored cone-nanolayer target

An advanced cone-nanolayer target with nanolayers on both inside and outside of the hollow-cone tip is proposed. Two-dimensional particle-in-cell simulations show that laser interaction with such cone-nanolayer targets can efficiently produce fast electron beams with manageable spotsize, and the beams can propagate for a relatively long distance in the vacuum beyond the cone tip.Physics, AppliedSCI(E)EI3ARTICLE4553-5583
