Description
Brookhaven National Laboratory (BNL) was chosen to host the international Electron-Ion Collider (EIC), which will collide high energy and highly polarized hadron and electron beams with a center of mass energy up to 140 GeV. The Interaction Region (IR) requires several large aperture, relatively high field superconducting dipole and quadrupole magnets, some of which are very closely spaced.
B1pF is a large aperture (300mm coil ID), medium field (4.2T), 3 meter long superconducting dipole magnet. Its size is larger than the largest superconducting magnet in the RHIC accelerator (180mm DX dipole, 4.2T, 3.7m L). As such, B1pF was chosen as the representative magnet to be prototyped to demonstrate the technological choice, design and construction details. This paper describes the analyses and considerations which informed both the magnet and magnet tooling designs, and construction results so far, in particular the plan for novel coil winding tooling and the test coil winding & curing program that was carried out prior to coil and magnet construction.
