Technology

ESS 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.

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 at ESS will take place when the accelerated proton beam hits the tungsten bricks of the 11-tonne target, producing unprecedented neutron brightness for scientific experiments across multiple disciplines.

Integrated Control System (ICS)

20 In-Kind Work Packages from 11 Institutes in 9 Countries

The Integrated Control System (ICS) for the European Spallation Source is a complex network of hardware, software and configuration databases that integrates the operations of all the various parts of the Accelerator, Target, Instrument and Conventional Facility infrastructures. It is based on the EPICS framework.
