A Miniature Transport-line Design for Laser Plasma accelerator-driven FELs using HTS Magnets

Laser-plasma acceleration is an outstanding candidate to drive the next-generation compact light sources and FELs. Due to extremely high accelerating gradients in LPAs, electron bunches can gain sufficient energies to generate synchrotron radiation in the X-ray regime in only a few millimetres to centimeters of acceleration length. To efficiently capture and transport the LPA-generated bunches in a compact transport line, beam line designs employing combined-function high-strength magnets based on high temperature superconductor technology have been studied. In this contribution we present the beam dynamics calculations as well as the magnet designs for a compact transport line matching the LPA-generated beam to a transverse-gradient undulator.
