Description
Superconducting Magnet Division, Brookhaven National Laboratory invented a unique superconducting magnet design and development technology which can be considered as 3D printing of Superconducting magnets. The magnets developed using this technology are known as Direct Wind Magnets. The magnets developed using this technology are deployed at several colliders, accelerators and experimental facilities across the world. These include HERA-II, SuperKEKB, BEPC, JPARC, Apha-3 at CERN, JPARC etc. This technology was the baseline design for main final focus quadrupoles for International Linear Collider (ILC) and the Electron Ion Collider (EIC) coming up at Brookhaven National Laboratory heavily depend on Direct Wind Technology for interaction region magnets. The corrector magnets for FCCee Interaction region are proposed to be built using this technology. The existing direct wind correctors in SuperKEKB will be replaced with newer correctors in SuperKEKB upgrade.
Direct Wind magnet technology is a novel method of constructing complex, multi-functional, multi-polarity, nested, compact, high homogeneity superconducting magnets without the need of custom tooling and fixtures for each new magnet project. In this technology, magnetic measurements at intermediate stages are integrated with production to carry out field harmonic compensation which helps in production of high homogeneity magnets.
This talk will detail this technology along with its usefulness and relevance for interaction region magnets of a high luminosity collider. Current projects and recent magnets produced using this technology will also be discussed along with brief design overview of ILC main final focus quadrupoles. Several advances are proposed for this technology including direct wind magnets using HTS, Nb3Sn, new cable design and incorporation of passive and active quench protection system. Direct Wind is one of BNL’s original contributions to Accelerator Science and technology.
