Next-generation plasma-based accelerators can push electron bunches to gigaelectronvolt energies within centimetre distances 1 , 2 . The plasma, excited by a driver pulse, generates large electric fields that can efficiently accelerate a trailing witness bunch 3 – 5 , enabling the realization of laboratory-scale applications ranging from high-energy colliders 6 to ultrabright light sources 7 . So far, several experiments have demonstrated large accelerations 8 – 10 but the resulting beam…
