Sextupole magnets are used extensively in particle ac-celerators, synchrotrons, and storage rings. Good magnet-ic field quality is needed in these magnets, which requires machining the magnet parts to high precision and is the primary driver of the high fabrication costs. To minimize the fabrication costs, a magnetic field quality study from tolerance analyses was conducted. In this paper, finite element analysis (FEA) using OPERA was performed to identify key geometric factors that affect the magnetic field quality and identify the allowable range for these factors. Next, geometric and dimensional tolerance stack-up analyses are carried out using Teamcenter Variation Analysis to optimize the allocation of the geometric tol-erances to parts and assemblies. Finally, the analysis re-sults are compared to magnetic measurements of a R&D sextupole magnet.
