To unlock broader applications of these beams, we need the ability to tailor the ion energy spectrum. Here, we present a scheme that achieves precisely this by accelerating protons in a \"lighthouse\" fashion, whereby the highest-energy component of the beam is emitted in a narrow cone, well separated from the lower-energy components.
