Advanced Design and Measurement Techniques for 90mm and 35mm Aperture Dipole Magnets

This document outlines the specifications and technological requirements for 90mm and 35mm aperture dipole magnets used in the NSLS SR project. It details the matching of pole ends to achieve a high-quality magnetic field (1.5 x 10^-4) and discusses equivalent magnetic field integrals in relation to the 90mm aperture dipoles. Additionally, it highlights the use of Hall sensors and NMR probes for precise magnetic measurements, assembly fixtures, and radiation-resistant materials. Comprehensive information on electric and water connections, as well as the overall construction integrity, is included.
