Led by France, Italy and the UK, ESS is Pushing Accelerator Technology to its Limits


In the final and major stages of acceleration before contact with the Target, the proton beam energy of the ESS Accelerator will reach 2.0 GeV, making it the most powerful linear proton accelerator ever built. France’s national Atomic and Alternative Energies Commission, CEA, is guiding the design, production and testing of the superconducting radio-frequency elliptical cryomodules that make this possible.
