Extensive prototyping of storage ring magnets is ongoing at the Advanced Photon Source (APS) in support of the APS Multi-Bend Achromat upgrade (APS-U) project. As part of the R&D activities 4 quadrupole magnets with slightly different geometries and pole tip materials, and one sextupole magnet with vanadium permendur pole tips were designed, built and tested. Magnets were measured individually using a rotating coil and a Hall probe for detailed mapping of the magnetic field. Magnets were then assembled and aligned relative to each other on a steel support plate and concrete plinth using precision machined surfaces to gain experience with the alignment method chosen for the APS-U storage ring magnets. The required alignment of magnets on a common support structure is 30 micron rms. Measurements of magnetic field quality, strength and magnet alignment after subjecting the magnets and assemblies to different tests will be presented.

	A project is underway at the Advanced Photon Source to mechanically straighten the thirteen 3 meter accelerating structures in the Linac in order to minimize transverse wakefield, and improve charge transport efficiency and beam quality. Flexure supports allow positioning of the structures in the X & Y directions. Mechanical design of the flexure support system, straightening techniques, mechanical measurement methods, and mechanical & RF results will be discussed.

A project is underway at the Advanced Photon Source to mechanically straighten the thirteen 3 meter accelerating structures in the Linac in order to minimize transverse wakefield, and improve charge transport efficiency and beam quality. Flexure supports allow positioning of the structures in the X & Y directions. Mechanical design of the flexure support system, straightening techniques, mechanical measurement methods, and mechanical & RF results will be discussed.
