A novel scheme for increasing the number of collisions in particle accelerators has boosted the performance of the world's highest-energy collider and promises to rev up others.

This scheme, called high-energy electron cooling, helped the Tevatron collider at Fermi National Accelerator Laboratory (Fermilab) in Batavia, Ill., last October to shatter the 23-year-old world record for particle-collision rates.

For decades, particle physicists have used electron cooling to control the properties of particles in low-energy accelerators, but they were daunted by the difficulty of high-energy cooling, comments beam-cooling specialist Fritz Caspers of the European Organization for Nuclear
