Construction and Test Results from 1.8 M-Long, 50 Mm Aperture SSC Model Collider Dipoles
A series of four 1.8 m-long model SSC dipole magnets has been constructed at BNL in order to test the new, wider 50 mm aperture SSC design prior to measurements of the full length 15 m-long dipoles. Except for the length, these magnets have the same baseline design and features as the full length models. All four short magnets were tested successfully, have exhibited reliable and uniform behavior, and have exceeded the 10% quench margin above the SSC operating point. In addition, some interesting results have led to further ongoing investigations into the effects of ramp rate on quench performance and magnetic multipoles, and into the effect of end force preload on training. This report will describe the basic features of the 50 mm design of these magnets and the experimental methods used in the testing of the magnets. Results from quench tests, ramp rate studies, strain gauge measurements, and magnetic field harmonic measurements will be presented.
