The proton-boron (pB) reaction has attracted extensive interest for confinement fusion since it produces energetic α particles without neutrons. Based on the pitcher-catcher geometry, a scheme to achieve a high-yielding pB nuclear reaction is proposed, where a meshed catcher target is used. The hot electrons generated by the interaction between laser and pitcher target induce a sheath field in the meshes that accelerates protons in the catcher target to drive a nuclear reaction.
