Stanford U's Fingernail-sized 'Particle-Accelerator on a Chip'; Glimmer of Hope amidst the Police State Lunacy?Submitted by AnCapMercenary on Wed, 10/02/2013 - 06:33
Or more toys for DARPA et al?
"Our sponsor of this work is DARPA [the Defense Advanced Research Projects Agency], and DARPA wants us to develop an accelerator and an X-ray source that can be portable so that you could carry the X-ray machine into the field and use it to provide medical care for injured soldiers," said Robert Byer, principal investigator of the study. - CSM, 9/30/2013

Menlo Park, Calif. — In an advance that could dramatically shrink particle accelerators for science and medicine, researchers used a laser to accelerate electrons at a rate 10 times higher than conventional technology in a nanostructured glass chip smaller than a grain of rice.
The achievement was reported today in Nature by a team including scientists from the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory and Stanford University.
“We still have a number of challenges before this technology becomes practical for real-world use, but eventually it would substantially reduce the size and cost of future high-energy particle colliders for exploring the world of fundamental particles and forces,” said Joel England, the SLAC physicist who led the experiments. “It could also help enable compact accelerators and X-ray devices for security scanning, medical therapy and imaging, and research in biology and materials science.”
Because it employs commercial lasers and low-cost, mass-production techniques, the researchers believe it will set the stage for new generations of "tabletop" accelerators.

Imagine an X-ray machine small enough to fit on a table top.
Stanford researchers have brought us one step closer to this technology by creating a particle accelerator smaller than a grain of rice. The device paves the way for cheaper and smaller accelerators that could mean big things for science and medicine.
"Our sponsor of this work is DARPA [the Defense Advanced Research Projects Agency], and DARPA wants us to develop an accelerator and an X-ray source that can be portable so that you could carry the X-ray machine into the field and use it to provide medical care for injured soldiers," said Robert Byer, principal investigator of the study.
Particle accelerators are typically clunky and costly. X-rays use accelerators to produce the images seen on film – electrons accelerated through a tube collide with atoms to create X-rays. Most accelerators use microwaves to accelerate the electrons to nearly the speed of light through a linear or circular track.
