This paper presents a 120-mm aperture 2-layer dipole coil with stress management (SM) using a cos-theta coil geometry. Additive manufacturing technology was used to print a plastic model of the coil support structure for practice coil winding, while the actual support structure was printed using 316 stainless steel. The paper reports the results of the SM structure size control and key coil fabrication steps, as well as presents and discusses the design of the coil SM structure and its finite element analysis (FEA) in dipole mirror test configurations.
This paper describes a 120-mm aperture 2-layer dipole coil with stress management (SM) developed at Fermilab based on cos-theta coil geometry. A model of the coil support structure made of plastic was printed using additive manufacturing technology and used for practice coil winding. The real coil support structure was printed using the 316 stainless steel. The results of the SM structure size control and the key coil fabrication steps are reported in the paper. The design of coil SM structure and the coil FEA in the dipole mirror test configurations are presented and discussed.
