Accelerator

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.

The ESS Accelerator Division is responsible for the requirements for all systems for the accelerator and assures that core know-how for the full system is secured at ESS.

External collaboration partners will do the major part of the design update work and a large part of the construction. They are operating with a collaboration guided by a collaboration agreement and with individual contracts for each collaborator with significant work at ESS.

The work of the Accelerator Division is overseen by the Accelerator Management Team (AccMT) and the Accelerator Technical Board (ATB). The ATB includes all work package leaders, the project management team and representatives for all the Accelerator partner institutes.
