Wired wonders :
... A team of German and Russian physicists have pioneered a new technique for particle acceleration, called proton-driven plasma-wakefield acceleration (PWFA). The technique may one day allow machines a fraction of the size of today's accelerators to create the highest-energy particles ever.
"This could be a major step forward," says Allen Caldwell of the Max Planck Institute for Physics in Munich, coauthor of the study, which appeared in Nature Physics Sunday. "The dream is that it will lead to much more compact — and therefore much cheaper — electron accelerators."
