Title A design study on the ESS spallation target and design considerations on the helium circulator
Abstract This report presents the results of a study carried out on the target of the European Spallation Source (ESS) by the High Power Targets Group at Rutherford Appleton laboratory over 2012 - 2014 under contract to ESS. The work focused on the design and thermo-mechanical analysis of the spallation target subjected to a 2.5 GeV, 5MW proton beam. Section 1 reports a study on the initial tungsten “stacked plates” baseline design which estimates temperature jumps in the plates resulting in high thermal stresses of the order of 340MPa. Section 2 proposes a design study of the target where segmentation of the tungsten plates is used as a mean to reduce the thermal mechanical stresses in the target material. A modular-type functional design of the target is then presented which offers increased ease of manufacturing, higher reliability and the possibility to perform remote maintenance of the target wheel. Finally Section 3 presents some design considerations on a helium circulator capable of delivering the 3kg/s mass flow rate required for the cooling of the target.
