The experiment requires a beam consisting of proton bunches approximately 200ns FW long, separated by 1.7 microseconds, with no out-of-time protons at the 10⁻¹⁰ fractional level. Satisfying this "extinction" requirement is very challenging. Simulations show that the formation of the bunches will result in an extinction of roughly 10⁻⁵. The remaining extinction will be accomplished by a system of resonant magnets and collimators, configured such that only in-time beam is delivered to the experiment.
