Laser light needn’t be as precise as previously thought to drive new breed of miniature particle accelerators, say Berkeley Lab researchers.

Making a tabletop particle accelerator just got easier. A new study shows that certain requirements for the lasers used in an emerging type of small-area particle accelerator can be significantly relaxed. Researchers hope the finding could bring about a new era of accelerators that would need just a few meters to bring particles to great speeds, rather than the many kilometers required of traditional accelerators. The research, from scientists at the U.S. Department of Energy’s (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab), is presented as the cover story in the May special issue of Physics of Plasmas.

AUSTIN, Texas — Physicists at The University of Texas at Austin have built a tabletop particle accelerator that can generate energies and speeds previously reached only by major facilities that are hundreds of meters long and cost hundreds of millions of dollars to build.

“We have accelerated about half a billion electrons to 2 gigaelectronvolts over a distance of about 1 inch,” said Mike Downer, professor of physics in the College of Natural Sciences. “Until now that degree of energy and focus has required a conventional accelerator that stretches more than the length of two football fields. It’s a downsizing of a factor of approximately 10,000.” (more…)

Go Ask ALICE: Learning About the Big Bang

Nearly 14 billion years ago, the universe began with a bang — a big one.

Scientists believe that the universe and everything within it began as an extremely hot, dense “soup” that eventually gave rise to galaxies, stars, planets and life and that continues to expand to this day.

Now scientists around the world are pushing back the frontiers of our understanding about the moment the universe was born using the Large Hadron Collider (LHC), a giant particle accelerator at CERN (the European Organization for Nuclear Research) near Geneva, Switzerland. (more…)

ANN ARBOR, Mich.— Under just the right conditions — which involve an ultra-high-intensity laser beam and a two-mile-long particle accelerator — it could be possible to create something out of nothing, according to University of Michigan researchers.

The scientists and engineers have developed new equations that show how a high-energy electron beam combined with an intense laser pulse could rip apart a vacuum into its fundamental matter and antimatter components, and set off a cascade of events that generates additional pairs of particles and antiparticles.
