Caption

The Laser Ablation Particle Acceleration and Observation (LAPAO) machine, built by Trinity’s Science & Technology in Advanced Manufacturing (STAM) research group, uses a laser to fire particles of 10–60 micronsin size at speeds of up to 1 km per second, which is about three times faster than a bullet. A special camera, taking a billion pictures per second, then captures how these particles behave when they hit a surface: do they stick, bounce, or break?
