摘要: We present a first on-chip positron accelerator based on dielectric laser acceleration. This innovative approach significantly reduces the physical dimensions of the positron acceleration apparatus, enhancing its feasibility for diverse applications. By utilizing a stacked acceleration structure and far-infrared laser technology, we are able to achieve a seven-stage acceleration structure that surpasses the distance and energy gain of using the previous dielectric laser acceleration methods. Additionally, we are able to compress the positron beam to an ultrafast sub-femtosecond scale during the acceleration process, compared with the traditional methods, the positron beam is compressed to a greater extent. We also demonstrate the robustness of the stacked acceleration structure through the successful acceleration of the positron beam.
