  The European Spallation Source target system is, together with the proton linac, the main component in the spallation process. ESS will use a 4-ton, helium-cooled, rotating tungsten target for this purpose, and its protection and availability is paramount to the success of ESS. High demands are placed on all of the target equipment, including cooling, movement, rotation, and timing, in order to reach the facility-wide 95% availability goal for neutron production. Machine protection has defined a set of protection functions that are to be implemented for the target system. This paper describes the development of these protection functions through the use of classic HAZOPs combined with modern safety standard lifecycle management. The implementation of these functions is carried out through close collaboration between the target system owners and the machine protection group at ESS.
