Before a Muon Collider or a Neutrino Factory can be built, these new types of accelerator facility must be designed, and the designs simulated to assess and optimize their performance. The design process begins with initial concepts of what might work, followed by increasingly sophisticated simulations to sort out what will work, how well it will work, and what sort of performance will be required for the constituent components. Muon Colliders and Neutrino Factories are ambitious new facilities, and in designing them many new concepts must be invented, and technology must be pushed beyond the present state-of-art.
The design and simulation process begins by focusing independently on the big subsystems: The front-end proton accelerator, the proton target and pion collection system, the muon beam forming systems, the muon cooling channel, the acceleration system, and the muon storage ring. Ultimately these subsystems must be fit together, with an end-to-end simulation of the entire system. Poorly performing or cost ineffective parts of the overall design can then be identified and improved upon.
