Scientists Create a Particle Accelerator That Fits on a Chip

Scientists at Stanford and SLAC have created a silicon chip that can accelerate electrons by using an infrared laser to deliver a similar energy boost that takes microwaves many feet. In a January issue of Science, a team led by an electrical engineer, Jelena Vuckovic, conveyed how he carved a nanoscale channel out of silicon, sealed it in a vacuum and sent electrons through an opening while beams of infrared light were transmitted by the channel walls to speed the electrons along. The accelerator-on-a-chip demonstrated in Science is just a prototype. However, Vuckovic said its design and fabrication techniques could be scaled up to deliver particle beams accelerated enough to perform cutting-edge experiments in chemistry. "The largest accelerators are like powerful telescopes. There are only a few in the world and scientists must come to places like SLAC to use them," Vuckovic said. "We want to miniaturize accelerator technology in a way that makes it a more accessible research tool." "We can derive medical benefits from the miniaturization of accelerator technology in addition to the research applications," Solgaard said.
