      abstract     = {High-brightness electron bunches drive fundamental research
                      in particlephysics and photon science. Key to achieving a
                      high brightness is to have a lowtransverse emittance, which
                      ensures that the bunch can be tightly focussed.
                      Inradiofrequency accelerators a low initial emittance can be
                      rapidly degradeddue to space charge forces, which are
                      greatly diminished once the electronbunch attains a
                      relativistic velocity. A plasma accelerator can maintain
                      orders-of-magnitude higher accelerating fields than
                      radiofrequency accelerators,while multiple techniques exist
                      to create a low emittance electron bunchdirectly inside the
                      plasma accelerator structure. Plasma accelerators
                      thereforeoffer a possibility to create high-brightness
                      bunches in wakefields driven evenby low-quality drive
                      bunches. Here we demonstrate the injection and
                      gigavolt-per-metre acceleration of electron bunches with
                      mm-mrad normalised emit-tance, O(10 pC/MeV) spectral density
                      and per-cent-level energy spread, all withexcellent
