A 1-m long superconducting dipole prototype with an aperture of 5 cm and a rated field of 6.6 T was built and tested. This model was based on a two-layer cosine-theta coil clamped by stainless steel collars inside a laminated iron yoke, with a large keystone-angle cable and no wedge. The cold mass was encased in an outer stainless steel skin. The magnet was instrumented with voltage taps, which allow the location of the quench start, and with strain gauges, which allow the measurement of the coil stress variations during assembly, cool-down, and energization. Prior to the assembly, several tests were carried out in order to understand the mechanical properties of the coil and to determine a proper calibration for the strain gauges. This paper reports these design studies, with emphasis on the calibration problem, followed by a discussion of the magnet assembly and quench performance in light of the mechanical measurements.
