      abstract     = {Plasma waves generated in the wake of intense, relativistic
                      laser1,2 or particle beams3,4 can accelerate electron
                      bunches to gigaelectronvolt energies in centimetre-scale
                      distances. This allows the realization of compact
                      accelerators with emerging applications ranging from modern
                      light sources such as the free-electron laser to energy
                      frontier lepton colliders. In a plasma wakefield
                      accelerator, such multi-gigavolt-per-metre wakefields can
                      accelerate witness electron bunches that are either
                      externally injected5,6 or captured from the background
                      plasma7,8. Here we demonstrate optically triggered
                      injection9,10,11 and acceleration of electron bunches,
                      generated in a multi-component hydrogen and helium plasma
                      employing a spatially aligned and synchronized laser pulse.
                      This ‘plasma photocathode’ decouples injection from wake
                      excitation by liberating tunnel-ionized helium electrons
                      directly inside the plasma cavity, where these cold
                      electrons are then rapidly boosted to relativistic
                      velocities. The injection regime can be accessed via
                      optical11 density down-ramp injection12,13,14,15,16 and is
                      an important step towards the generation of electron beams
                      with unprecedented low transverse emittance, high current
                      and 6D-brightness17. This experimental path opens numerous
                      prospects for transformative plasma wakefield accelerator
                      applications based on ultrahigh-brightness beams.},
