Modular Design and Modular Program for High Gradient Quadrupoles

A modular design and modular program is introduced here for high gradient quadrupoles. The proposed quadrupole design is based on simple flat racetrack coil modules. Even though many high gradient quadrupole designs using flat racetrack coils have been considered earlier, they have not been able to generate the same maximum quench gradient as produced in conventional cosine (two) theta designs. The proposed modular design is able to overcome those limitations. In addition, a systematic, flexible and cost-effective modular R&D program is also proposed that can be used in developing both high gradient quadrupoles and a variety of high field dipoles. A rapid turn around magnet R&D program based on flat racetrack coils has been found very useful and efficient in the past. Since the proposed modular design is based on simple flat racetrack coils with large bend radii, it offers good likelihood of success in both React & Wind and Wind & React technology for building magnets with brittle superconductors.
