Fig. 1. (Color online) Schematic of the symmetric DLA structure. DLA acceleration cavities are placed with micro-prisms from both sides, where the input laser pulses are injected from both top and bottom directions. In the figures, h is the cavity height, θ is a prism angle of the micro prism, Λ is a period of the acceleration cavities, wg is a gap in the acceleration channel, and the injected electrons are accelerated to the positive x-direction. The material of the substrate colored with red and the material of the cavity colored with cyan are Si. The micro-prism colored with white consists of SiO2.
