	We have performed 3D particle tracking in realistic magnetic field configuration to study particle losses in the SNS ring injection dump beam line and beam profile tilt in the extraction Lambertson septum. The technique is based on accurate 3D modeling of magnet assemblies or beam lines and 3D particle trajectory calculations through the simulated field. The studies have discovered a number of design and operation issues that cause particle losses in the injection region and beam profile tilt through the extraction septum. The remedies to all the problems are also devised. This paper reports our simulation techniques and major findings.
