Abstract :
The paper presents the results of a conceptual design study of double aperture Nb3Sn dipole magnets for VLHC based on the cos-theta and common coil geometry with cold and warm iron yoke. The study included an optimization of the iron yoke geometry to achieve the maximum transfer function, small fringe fields and low-order field harmonics as well as an optimization of the coil geometry to correct a quadrupole field component (normal or skew) inevitable for 2-in-1 magnet designs
