Description
The Electron-Ion Collider (EIC), a new facility to be built in the United States at the U.S. Department of Energy’s Brookhaven National Laboratory in collaboration with Thomas Jefferson National Accelerator Facility. The EIC project will provide us answers to the mysteries of the origin of mass and building blocks of our universe.
There are many different types of superconducting magnets near the interaction region (IR) of EIC: traditional collared dipole and quadrupole magnets and tapered canted-cosine theta (CCT) and serpentine magnets. The direct wind technology, pioneered by BNL, will be used to build those CCT and serpentine magnets.
A 6-around-1 NbTi cable will be used for CCT and serpentine magnets. Given the relatively smaller conductor used for those direct wind magnets, the overall engineering current density will be 2-3 times higher in comparison to traditional collared magnets in EIC. This is technically challenging and potentially represents high risks for quench protection.
In this paper we use different tools and methods for quench simulation for several EIC direct wind magnets. We also present results of a sensitivity study, exploring different material properties and Jc curves. This paper also discusses and validates the quench simulation results with measurement results from a small-scale serpentine magnet tested at BNL in October 2024.
