CEA elliptical cavity prototype

Technology

The European Spallation Source will be one of the most technologically advanced Big Science facilities on the planet. It will host the world's most powerful linear proton accelerator, the first target system of its kind, the most efficient moderator-reflector system ever designed and 1.68 million facility control points.

Accelerator Systems

42 In-Kind Work Packages, from 18 Institutes, in 8 Countries

The ESS accelerator high level requirements are to provide a 2.86 ms long proton pulse at 2 GeV at repetition rate of 14 Hz. This represents 5 MW of average beam power with a 4% duty cycle on target.

Target Systems 

21 In-Kind Work Packages from 7 Institutes in 6 Countries

The spallation process takes place when the accelerated proton beam hits the Tungsten bricks of the 11-tonne target disk. At ESS, this will produce unprecedented neutron brightness for scientific experiments across multiple disciplines.
