This paper presents the design concept of the dipole magnet with 50 mm aperture, 20 T nominal field and 13% margin based on a six-layer cos-theta (CT) hybrid coil design. Due to the high stresses and strains in the coil at high field, Stress Management (SM) elements are implemented in the CT coil geometry. The results of magnet magnetic analysis are presented and discussed. The key parameters of this design are compared with the parameters of similar magnets based on block-type and canted cos-theta coils.

    A strand-level finite-element model of Fermilab's Bi-2212 cos-theta insert shows a maximum Von Mises stress of 68 MPa in the superconductor at 10 kA, below the 120 MPa design limit.
