Muon1 DPAD (v4.0-4.2)

Muon1 Distributed Particle Accelerator Design

The experiment is called the Neutrino Factory, scheduled for construction some time from 2015. Its primary aim is to fire beams of neutrinos (fundamental particles) through the Earth's interior to detector stations on different continents. They're doing this to measure whether they change type en route (there are 3 types of neutrino) and data from this in turn will allow them to determine the neutrino's mass more accurately.

You are simulating the part of the process where the proton beam hits the target rod and causes pions to be emitted, which decay into muons. These would then proceed to a storage ring and decay into electrons and the neutrinos that are used for experiments.
