A series of full-scale demonstration SSC collider dipole magnets were built for the ASST. These magnets, DCA311 through DCA319, have 50 mm aperture and 15 m magnetic length with 6.6 Tesla uniform field. For the support structure of the W6733B cross section, the Fermilab design uses a vertical split in the yoke. The end sections of the magnet have solid spacers and are supported by collet clamps. The splices between inner and outer coils are made in preforms which lie outside of the high field region. The magnets were produced in pipeline fashion with no intentional major changes between magnets. As a part of the technology transfer program, the last 7 magnets were built by General Dynamics personnel using the magnet construction facilities of Fermilab, while the first two magnets were built entirely by Fermilab personnel. At present, the magnets up to DCA316 have been tested at Fermilab. The general characteristics of the magnets have been quite satisfactory. Both of the Fermilab built magnets have reached the conductor limited field strength with no significant training. Two of the General Dynamics built magnets each required a single training quench. However, all of the magnets tested up to date meet the ASST specifications. This report describes the mechanical properties of the ASST magnets at Fermilab based on the currently available test results.
