Mechanical behavior of Fermilab-built 1.5 m model SSC collider dipoles

Several model SSC collider dipole magnets (50 mm aperture, 1.5 m magnetic length) have been built and tested at Fermilab. These magnets are instrumented with strain gauges to measure stresses in the coil, the cold mass shell, and the coil end clamp assembly. Measurements are made of these quantities during assembly, cooldown, excitation, and warmup. Additional mechanical measurements are made on magnet sub-assemblies during manufacturing. Data from these measurements are presented and compared with expectations from the design calculations.
