Intense muon beams have many potential applications, including neutrino factories and muon colliders. However, muons are produced in tertiary beams into a diffuse phase space. To make useful beams, the muons must be rapidly cooled before they decay. A promising new concept for the collection and cooling of muon Pion-Decay and Muon-Transport Section Pion Capture Section A section to capture pions with a large magnetic field by superconducting maget A detector to search for muon-to-electron conver-sion processes. A section to collect muons from decay of pions under a solenoi-dal magnetic field. Detector Section Pion-Decay and Muon-Transport Section decreases the diameter of the helical spiral of the decay muons, increasing the capture rate, and a field of 4.7Tesla has been found to be optimal in the current design.

Pion decay to muon

Why do pions decay into muons and not electrons? [Note: this requires some background in undergraduate-level particle physics.] One might expect that if a charged pion can decay into a muon and a neutrino, then it should also go into an electron and a neutrino.

The negative pion decays into a muon and a muon antineutrino as illustrated below. pion, muon, neutrino A pion (mπ = 273 me) at rest decays into a muon (mμ = 207 me) and a neutrino (mν = 0). Find the kinetic energy and momentum of the muon and the neutrino in MeV. Solution by Michael A. Gottlieb: (I choose units such that c = 1, and assume that me = 0.511MeV.) Since the pion is at rest conservation of momentum dictates that the momenta of the Marietta Kurz was the first person to detect the unusual "double meson" tracks, characteristic for a pion decaying into a muon, but they were too close to the edge of the photographic emulsion and deemed incomplete.
