This thesis presents work done in the context of the Neutrino Intensity Frontier. Cross section measurements for charged current coherent pion production by neutrinos and antineutrinos on argon are presented. These measurements are performed using the Argon Neutrino Test (ArgoNeuT) detector exposed to the NuMI beam at Fermilab. The cross sections are measured to be 2.6^{+1.2}_{-1.0}(stat)^{+0.3}_{-0.4}(syst) x 10^{-38} cm2 per argon nucleus for neutrinos at a mean energy of 9.6 GeV and 5.5^{+2.6}_{-2.1}(stat)^{+0.6}_{-0.7}(syst) x 10^{-39} cm2 per argon nucleus for antineutrinos at a mean energy of 3.6 GeV. This is the first time this interaction has been measured in argon and the first time it has been measured using an automated analysis. In the context of the Muon Ionization Cooling Experiment (MICE), the later chapters of this thesis present work concerning the precise tracking of muons in the MICE detectors which will be fundamental for the demonstration of ionization cooling. The relation between MICE, the Neutrino Factory and nuSTORM is explored in the early chapters of this thesis and the physics potential of neutrino beams from the decay of muons is reviewed.
