Scientists at the Compact Particle Acceleration Corporation are developing a 13-foot-long particle accelerator that costs about $30 million. Most accelerators use large magnets to generate the electromagnetic field that pushes charged particles. The magnets require 10-foot-thick concrete shielding and bulky hardware. CPAC’s prototype creates the electromagnetic field with electric lines, which don’t require massive shielding or large additional equipment. The new accelerator could be commercially available as soon as 2015.
