Coupling 2 ‘tabletop’ laser-plasma accelerators: A step toward ultrapowerful accelerators

Laser-plasma accelerators (LPAs) got the nickname “tabletop” because, as shown by the unique BELLA accelerator at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), they can boost electron beams to multibillion electron-volt energies (GeVs) in a few centimeters–a distance thousands of times shorter than conventional accelerators.
