Abstract: In a plasma accelerator, a laser or particle beam excites a plasma wave that can sustain orders of magnitude higher electric fields than the RF-cavities of conventional accelerators. These compact devices have the potential to drive next-generation free-electron lasers (FEL) of reduced size and cost. However, the highly sensitive FEL mechanism imposes strict requirements on the electron beam properties. So far, the quality of plasma accelerated beams cannot compete with that of conventional accelerators. Successfully driving the self-amplifying process demands the development of methods with increased control of the beam’s phase space - in combination with novel FEL designs that leverage the unique features of the plasma accelerated beams. Demonstrating a plasma-driven FEL therefore heavily relies on theoretical studies and requires numerical models that correctly represent the physics involved under the restriction of limited computational resources. Here, we present our recent work towards a plasma-driven FEL, based on the particle-in-cell (PIC) code FBPIC, and the non-averaging 3D FEL code PUFFIN.
