More Information: Because of the increased rate of muon decays and the more demanding goals in systematic uncertainties,
the collaboration had to devise improved instrumentation. The kicker that inserts the muons in the storage
ring will be entirely new and is optimized to give a precise kick on the first turn only, increasing the stored
fraction. The magnetic field will be even more carefully prepared and monitored. The detectors and
electronics are entirely new, and a state-of-the-art calibration system will ensure critical performance
stability throughout the long data taking periods. New in situ trackers will provide unprecedented
information on the stored beam.The first physics data-taking is expected in mid 2017.
