abstract = {{The European Spallation Source, ESS, is a source of spallation neutrons used for neutron scattering experiments, complementary to synchrotron light sources. ESS has very ambitious goals and experimentation with neutrons at ESS should be one or two orders of magnitude more performing compared to other sources. Each proton beam pulse generated by the linear accelerator will have a peak power of 125 MW. The machine’s equipment must be protected from damage due to beam losses, as such losses could lead to melting of e.g. the beam pipe within less than 5 microseconds. System-of-Systems engineering has been applied to deploy systematic and robust protection of the ESS machine. The ESS Machine Protection System of Systems (MP-SoS) consists of large-scale distributed systems, of which the components themselves are complex systems. Testing, verification and validation of the MP-SoS is rather challenging as each constituent system of the MP-SoS has its own management, functionality that is not necessarily designed for protection, and also the different system owners follow their own verification strategies. In this paper, we will present our experience gained through the first 3 beam commissioning phases, ESS has gone through so far. We will describe how we managed to declare MP-SoS to being ready for beam operation without complexifying the task, and we will present the challenges, issues, and lessons learned faced during the verification and validation campaigns. }},
