The FLASHForward facility at DESY provides a unique opportunity for the study of Plasma Wakefield Acceleration (PWFA). At FLASHForward, a several kA electron beam with energies up to 1.25 GeV interacts with a plasma in a dedicated windowless, differentially pumped beamline. The FLASHForward X-1 experiment focuses on the development and study of internal injection techniques to produce ultra-high quality, fs-length electron bunches. Pulses from a 25~TW, fs-class, synchronised laser system allow for selective dual-arm pre-formation of density down-ramp. In this work we present the first demonstration of highly stable internal injection at FLASHForward on density-downramps.
