Latest in miniaturization: Particle accelerator on a chip

This image, magnified 25,000 times, shows a section of an accelerator-on-a-chip. The gray structures focus infrared laser light (shown in yellow and purple) on electrons flowing through the center channel. By packing 1,000 channels onto an inch-sized chip, Stanford researchers hope to accelerate electrons to 94 percent of the speed of light. (Image credit: Courtesy Neil Sapra)

Just as engineers once compressed some of the power of room-sized mainframes into desktop PCs, so too have Stanford researchers shown how to pack some of the punch delivered by today’s ginormous particle accelerators onto a tiny silicon chip.
For the first time, scientists at Stanford and SLAC have created a silicon chip that can accelerate electrons
The accelerator-on-a-chip demonstrated in Science is just a prototype
“We want to miniaturize accelerator technology in a way that makes it a more accessible research tool.”
“In this paper we begin to show how it might be possible to deliver electron beam radiation directly to a tumor, leaving healthy tissue unaffected,” said Byer
“We can derive medical benefits from the miniaturization of accelerator technology in addition to the research applications,” Solgaard said.
