Description
A compact collinear wakefield accelerator has been developed for an X-ray free-electron laser operating at X-ray pulse repetition rates in the tens of kilohertz. The maximum achievable accelerating gradient is evaluated, with its upper limit constrained by beam breakup instability. Key fabrication techniques for the accelerator’s principal components—including wakefield generation structures, excess-power extraction couplers and diagnostics, focusing quadrupoles, and a novel undulator—are presented. Results from both laboratory and electron beam-based tests are compared with design specifications, showing strong agreement. Finally, prospective directions for future research are outlined.
