World's Longest Accelerator Probes Universe's Tiniest Particles
Scientists at the Stanford Linear Accelerator, or SLAC, labs have won three Nobel prizes and are currently amassing the first scientific evidence that there is more matter than antimatter in the universe, by smashing positrons and electrons together.
The lab's next big project, the Linac Coherent Light Source, will go online next year. Its X-ray free electron laser will be roughly 10 billion times more powerful than existing X-ray sources and let researchers capture movies of atoms and molecules during chemical reactions.
