Transverse collection of pions

The early stages of a neutrino factory are critical to fulfil physics requirements in the final muon storage ring. The transverse collection of pions behind the target is therefore a crucial feature for which different options exist. In this article, two collection systems using either quadrupoles or a transition solenoid between the target and the downstream channel are studied. The transition optics from the solenoid to a quadrupole channel is also discussed. Some figures of merit such as maximum transverse momentum captured or radial acceptance are compared as well as the technical challenges for each solution.
