Building compact particle accelerators: Bunching electrons can get more done

In the world of particle accelerators, laser wakefield devices are the small, but mighty upstarts. The machines can accelerate electrons to near the speed of light using a fraction of the distance required by conventional particle accelerators. However, the electrons are not all uniformly accelerated and beams with a mix of faster (higher energy) and slower (lower energy) particles are less practical.
