New Technique for Monitoring the Size of Low-Intensity Beams at Plasma-Wakefield Accelerators

The principle of laser wakefield accelerators: A high-power laser excites a charge wave in a plasma, which propagates at the speed of the laser pulse and pulls electrons behind it in its "wake", thus accelerating them.
