ENGINEERING SEMINAR 
  
The European Spallation Source and its Safety Protection Systems 
  
Annika Nordt 
European Spallation Source 
  
The European Spallation Source ( ESS ) located in Lund , Sweden, is currently in its construction phase, and includes a linear accelerator, sending 2.86 ms long pulses of 2 GeV protons at 14 Hz to a rotating tungsten target with an average power of 5 MW. This spallation source distributes thermal and cold neutrons to a large variety of state-of-the-art neutron instruments, at which researchers from academia and industry will investigate scientific questions. ESS plans to deliver its first neutrons in 2019 and reach its full design specifications in 2025, with a suite of 22 research instruments. Decommissioning is foreseen to start in 2065. 
  
An overview on the design of different protection and safety systems, such as the Machine Protection System ( MPS ), Personnel Safety System ( PSS ) and the Target Safety System ( TSS ) will be presented. 
  
Fulfilling the demanding requirements for ESS on reliability and an overall beam availability of 95%, a first statistical reliability model has been developed. The impact of an early reliability modeling on the design of safety and mission critical systems will be presented as well.
