    "abstract": "A new superferric magnetic storage ring with highly homogeneous field at 1.45\nT and weak electrostatic focussing is described which has been set up at the\nBrookhaven National Laboratory (BNL), USA, for a precision measurement of the\nmagnetic anomaly of the muon. The toroidal storage volume has a radius of 7 m\nand a diameter of 9 cm. Precision magnetic field determination based on pulsed\nNMR on protons in H$_2$O yields the field to better than 0.1 ppm everywhere\nwithin the storage region. Follow on experiments using the setup have been\nalready suggested to search for a finite mass of the muon neutrino and to\nsearch for an electric dipole moment of the muon with significantly increased\naccuracy. The high homogeneity of the field suggests the usage of such devices\nas a mass spectrometer for heavier particles as well.",
