Helium Cooled Target Concept for the ESS 5MW Target

Since the very beginning of the Pre-construction phase (2010-2012) of the European Spallation Source program, a Helium gas-cooled target was proposed, capable of sustaining the beam power of 5 MW. This avoids cladding of tungsten blocks necessary to mitigate corrosion in water-cooled systems. The concept of a stationary granular target filled with tungsten spheres of about 10mm diameter and inspired by previous studies proposed for neutrino factories, was first considered. The extension of this concept to a rotating target filled with tungsten rods represents a viable option for the ESS target. The neutronics performance, heat removal, ease of licensing, maintainability and cost are the most relevant criteria to be considered for target selection.
