Design Parameters of Insertion Region Magnets for VLHC-2 Flat Beam Optics
1. D1A has higher field and lower aperture. Lower aperture means less accumulated forces. Can be built with Nb3Sn or “BSCCO, Nb3Sn hybrid”.
2. The gradient in Q1A is lower due to a superimposed non-zero dipole field.
Designs based on the Nb3Sn and other materials available today.
