We propose to develop a compact laser-driven dielectric electron accelerator system over the course of three years that could be used for driving future x-ray free-electron lasers. This compact accelerator system will incorporate a high brightness laser-triggered photocathode source integrated with an on-chip laser accelerator network, as well as the associated fiber drive laser system. Thorough simulation and modeling of the accelerator structures will be used to build upon the foundation we have already established to improve the accelerating gradient and efficiency at both-on-relativistic and relativistic energies. These designs will be prototyped and tested using a modular electron-optic column custom designed for these experiments that will allow the testing of accelerator, focusing, and beam steering structures as well as high brightness electron sources. Over the course of the project, these components will be integrated together to form the basis for the compact laser driven source of attosecond bunched, relativistic electrons for future x-ray free electron lasers and high energy physics experiments.
