Field harmonics offer a powerful tool to examine the mechanical structure of accelerator magnets. A large deviation from the nominal values suggests a mechanical defect. Magnets with such defects are likely to have a poor quench performance. Similarly, a trend suggests a wear in tooling or a gradual change in the magnet assem-bly or in the size of a component. This paper presents the use of the field quality as a tool to monitor the magnet production of the Relativistic Heavy Ion Collider (RHIC). Several examples are briefly described. Field quality analysis can also rule out a suspected geometric error if it can not be supported by the symmetry and the magnitude of the measured harmonics.
