The realisation of high quality (high brightness and low energy spread) electron beams from plasma Wakefield accelerators is crucial for the advancement of fields such as photon science and future high-energy physics colliders. The FLASHForward facility is a pioneering dedicated beam-driven wakefield experiment combining the 1 GeV, 2.5 kA, FLASH electron beam and a 25 TW, 25 fs pulsed laser [1]. The Experiment 1 (X-1) branch of the project aims to produce and study such high-quality, high- brightness beams from a centimetre scale plasma cell. In preparation for the experimental runs in FLASHForward X-1, exploratory numerical studies are run using the OSIRIS particle in cell (PIC) code to study injection from a density down-ramp (DDR) [2] triggered and produced by a transverse ionisation laser [3]. Additional investigations are made into the effects arising from the intrinsic properties of the plasma channel, including the the wake structure resulting from a narrow plasma channel. [1] A.
