	The ESS, consisting of a pulsed proton linear accelerator, a rotating spallation target designed for an average beam power of up to 5 MW, and a suite of neutron instruments, requires a large variety of instrumentation, both for controlling as well as protecting the different hardware systems and the beam. The ESS beam power is unprecedented and an uncontrolled release could lead to serious damage of equipment installed along the tunnel and target station within only a few microseconds. Major failures of certain equipment will result in long repair times, because it is delicate and difficult to access and sometimes located in high radiation areas. To optimize the operational efficiency of the facility, accidents should be avoided and interruptions should be rare and limited to a short time. Hence, a sophisticated machine protection system is required. In order to stop efficiently the proton beam production in case of failures, a Fast Beam Interlock (FBI) system with a targeted reaction time of less than 5 microseconds and very high dependability is being designed. The design approach for this FPGA-based interlock system will be presented as well as the status on prototyping.

	ESS is facing extremely high beam availability requirements and is largely relying on custom made, very specialised, and expensive equipment for its operation. The proton beam power with an average of 5MW per pulse will be unprecedented and its uncontrolled release can lead to serious damage of the delicate equipment, causing long shutdown periods, inducing high financial losses and, as a main point, interfering drastically with international scientific research programs relying on ESS operation. Implementing a fit-for-purpose machine protection concept is one of the key challenges in order to mitigate these risks. The development and realisation of the measures needed to implement such concept to the correct level in case of a complex facility like the ESS, requires a systematic approach, and will be discussed in this paper.

The European Spallation Source (ESS) is a collaboration of 17 European countries to build the world's most powerful neutron source for research.
