Abstract :
The authors describe the overall Hybrid III system, present test results, and indicate future plans. Hybrid III, completed in late 1991, has since undergone a sequence of tests in preparation for becoming a facility magnet. When first tested in December 1991, it generated a total central field of 33.5 T. The superconducting magnet (SCM), operating in a bath of superfluid helium at 1.65 K and with a current of 2200 A, contributed 12.7 T to the total. In subsequent runs it was shown that the SCM would reach a critical current of approximately 2230 A when operated at approximately 1.7 K. After the completion of improvements to the cryogenic components as described, two major goals were set: to reach 35 T in two steps and to operate Hybrid III as a facility magnet. Hybrid III is targeted to reach 35 T in the spring of 1993.<>
