Trinity College Dublin Develops Advanced Machine to Observe Micro-Particle Impacts

According to foreign media reports, researchers at the School of Engineering at Trinity College Dublin have developed a powerful new machine that can precisely observe the behavior of tiny particles, far smaller than a grain of sand, as they impact surfaces at extremely high speeds. The Laser Ablation Particle Acceleration and Observation (LAPAO) machine, created by the Advanced Manufacturing Science and Technology (STAM) research group at Trinity College Dublin, uses lasers to launch particles ranging from 10 to 60 micrometers in size at speeds of up to 1 kilometer per second, which is about three times the speed of a bullet. A special camera can capture up to one billion photos per second, documenting whether the particles adhere, bounce, or shatter upon impact.
