Operational Experience With the MICE Spectrometer Solenoid System

The Muon Ionization Cooling Experiment located at Rutherford Appleton Laboratory in England utilizes a superconducting solenoid system for the muon cooling channel that also holds particle-tracking detectors and muon absorbers inside their bores. The solenoid system installation was completed in summer of 2015 and after commissioning the system it has been running successfully. This paper summarizes the commissioning results and operational experience with the magnets focusing on the performance of the two spectrometer solenoids built by the U.S.
