Commissioning and first results of the Fermilab Muon Campus

Abstract

In the following years, the Fermilab Muon Campus will deliver highly polarized muon beams to the Muon g−2 experiment. The Muon Campus contains a target section wherein secondaries are produced, the delivery ring which separates the muons from the rest of the beam, and a sequence of beam lines that transports them to the Muon g−2 storage ring. Here, we report the first results of beam measurements at the Muon Campus with an emphasis on the key achievements that have contributed to the successful beam delivery to the Muon g−2 experiment. These achievements include the production of an intense secondary beam from the target, its transport over 2 km, the successful monitoring of muons from the available diagnostics, and the development of techniques for measuring the transverse optics. We also present detailed comparisons between the experimental data and simulation and discuss the similarities and differences observed.
