Description
The Electron-Ion Collider (EIC) plans to have a number of unique superconducting magnets in its interaction region (IR) to satisfy challenging requirements. As a test bed for addressing several R&D challenges in the development of Rutherford cable magnets with very large apertures, B1pF is currently being built as a full-length prototype at the Superconducting Magnet Division at Brookhaven National Laboratory (BNL). Designed as a single layer coil of NbTi Rutherford cable, B1pF has a coil inner aperture diameter of 300 mm and a total length of 3 m. To address the construction challenges at the same time to meet the stringent field quality and cross-talk requirements in the heavily space limited interaction region, the design is aimed to include maximum flexibility to compensate for any construction tolerances. This contribution discusses 2D and 3D design choices with a focus on magnetic shimming and 3D coil end optimizations based on trial winding iterations and feeding back of these results into the electromagnetic design.
