BELLA Table Top Laser (1 of 3) (IMAGE) DOE/Lawrence Berkeley National Laboratory Caption A laser pulse through a capillary filled with hydrogen plasma creates a wake that can accelerate an electron beam to a billion electron volts in just 3.3 centimeters. The same LOASIS accelerating structure has been modified to tune stable, high-quality beams from 100 to 400 million electron volts.
