Cooler and Cheaper Colliders

Scientists at CERN are currently studying the feasibility of a 100 tera-electron-volt (TeV) particle accelerator that produces 7 times more energy per collision than the Large Hadron Collider (LHC). Compared to the LHC, this future collider would have a circumference nearly 4 times as long and radiate 1000 times the power, an unprecedented amount of heat. Cooling the collider would be prohibitively expensive using current methods. But a new cooling scheme proposed by Roberto Cimino, of the INFN National Laboratory of Frascati, Italy, and CERN, would use significantly less energy, keeping the costs more manageable.
