Abstract :
The production of two types of superconducting multi-function magnets, needed for the HERA Luminosity Upgrade is underway at BNL. Coil winding is now completed and cryostat assembly is in progress. Magnet type GO and type GG cold masses have been satisfactorily cold tested in vertical dewars and the first fully assembled GO magnet system has been horizontally cold tested and shipped to DESY. Warm measurements confirm that the coils meet challenging harmonic content targets. In this paper, the authors discuss GO and GG magnet design and construction solutions, field harmonic measurements and quench test results
