Target

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

The design of target system components has a direct impact on the number of neutrons that can be generated, and is therefore of utmost importance for the future scientific capabilities of the ESS facility.

The first step in this process is production of high-energy neutrons through a spallation process involving proton beam interaction with a Tungsten target. The fast, high-energy neutrons released in the spallation process are slowed down to suitable energies for experiments at ESS, and then delivered to the instruments through beam ports. Key features of the Target Station are the target itself, the neutron moderator and reflector system, and the neutron beam extraction system.

The Target Division is part of the ESS Machine Directorate with the responsibility to design, develop, procure, install, commission and test the systems needed to convert the energetic proton beam coming from the ESS accelerator to neutron beams that are utilized for experiments.

All Target Station systems require electrical and instrumentation design and development in order to meet power, grounding, cable routing, monitoring, and controls requirements.

At ESS, the Conventional Facilities (CF) Division is responsible for the civil design and construction of the facility, and the Integrated Control System (ICS) Division is responsible for the design, development and implementation of the monitoring and controls systems for the facility, including equipment protection and personnel safety systems.

Collaboration between the Target, CF, and ICS Divisions is an essential component in the successful completion of the Target Station.
