About this file
This is a technical interface drawing for a D1/3 Dipole Magnet component of the Electron Storage Ring, part of the Electron-Ion Collider (EIC) project at Brookhaven National Laboratory in Upton, New York.
The drawing specifies a laminated yoke magnet assembly with a maximum length of 111.5 inches, maximum width of 22.7 inches (including connections), and maximum height of 13.6 inches. Key design requirements include a 90mm minimum distance between coils for vacuum pipe installation, laminations shuffled from different lots to minimize magnetic field strength variations, and non-oriented lamination steel. The magnet must accommodate both 12 and 5 turn coil configurations with bus connections capable of supporting four 500MCM lugs along the back leg. The design includes provisions for lifting lugs with a minimum 3:1 safety factor, thermal protection via Elmwood Sensors thermal switches, water system fittings using Parker Fluid brass components, and trim coil terminal blocks (Eaton PN# 14002-6). Support locations on the girder must be accessible from the sides, with magnet lamination surfaces welded to girder supports at BNL. The drawing references BNL Technical Specification EIC-MSG-SPC-008 and Statement of Work EIC-MSG-SOW-017 for additional details. Vendors are encouraged to optimize manufacturability, long-term reliability, and cost effectiveness. The drawing was approved on February 12, 2025, with revision B issued on May 13, 2026, reflecting reduced overall length and updated export control notes.
