摘要： Dielectric laser accelerators (DLAs) are considered promising candidates for on-chip particle accelerators that can achieve high acceleration gradients. This study explores various combinations of dielectric materials and accelerated structures based on the inverse Cherenkov effect. The designs utilize conventional processing methods and laser parameters currently in use. We optimize the structural model to enhance the gradient of acceleration and the electron energy gain. To achieve higher acceleration gradients and energy gains, the selection of materials and structures should be based on the initial electron energy. Furthermore, we observed that the variation of the acceleration gradient of the material is different at different initial electron energies. These findings suggest that on-chip accelerators are feasible with the help of these structures and materials.
