外文摘要：We present a first on-chip positron accelerator based on dielectric laser acceleration.This innovative approach signif-icantly reduces the physical dimensions of the positron acceleration apparatus,enhancing its feasibility for diverse applica-tions.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 meth-ods.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.
