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.
This paper describes the overall design philosophy of the fourteen one-of-a-kind, unique superconducting magnets in the “Inner Interaction Region” on both sides of the detector. A summary of the style chosen for each of the magnets with design rationalizations will be presented. The impact of the very tightly spaced, consistently off-axis layout of forward side hadron magnets, from which difficulties result will be described. The many internal interfaces (vacuum, instrumentation, cryogenics, power supplies, detector, etc.) and associated issues thereof will be discussed. Installation issues and plans to date will be shown.
