Abstract :
Quadrupole magnets in the SNS Medium Energy Beam Transfer line (MEBT) are in close proximity to each other. The distance between iron cores of is comparable to the magnet aperture and therefore fringe fields of the magnets overlap. The magnetic field distribution of the SNS MEBT quadrupole magnets has been calculated using the 3-D MAFIA code. The effect of fringe field on beam dynamics is studied and corrections to quad settings are calculated
