Protons ride moving waves to reach record energy with long-pulse lasers

Imagine a proton catching a wave and surfing it to gain speed. While the imagery may seem wild, the premise of laser-driven ion acceleration has promise as an alternative to conventional accelerators. However, the ultrathin targets used to drive this increase in ion energy are vu
