A compact particle accelerator developed by the University of Texas at Austin, several national laboratories, and the Texas-based company TAU Systems has produced an electron beam with an energy of 10 billion electron volts (10 GeV). The accelerator, less than 20 m long, is among three in the United States capable of producing an energy level that high, though the other two are both approximately 3 km long.
“We can now reach those energies in 10 cm,” said Bjorn Manuel Hegelich, associate professor of physics at UT and CEO of TAU Systems, referring to the size of the chamber where the beam was produced.
