摘要

Purpose

The BEPCII Upgrade (BEPCII-U) project features a combined superconducting magnet with a higher-magnetic-field gradient to enhance collision energy. The superconducting quadrupole magnet (SCQ) within this project utilizes direct winding technology to wind serpentine coils, ensuring a stable, precise, and complete it efficiently within the specified time. Furthermore, considering the future demand for direct winding technology for diversified coil shapes in superconducting magnet projects, it is necessary to develop a new type of multi-shaped winding control software to address the challenges posed by complex winding tasks.

Methods

The direct wind control software consists of two core modules: the graphics user interface module and the computerized numerical control module, aiming to provide an intuitive and user-friendly operating platform that allows users to easily control the winding machine.

Result

Through simulation testing, it has been confirmed that this software accurately winds various superconducting coil structures, including complex multi-shaped and multi-functional designs. Utilizing this winding control software, we successfully completed the winding task for the coil of the combined superconducting magnet using the winding machine. Further low-temperature magnetic field measurements indicate that the magnetic field performance of the wound SCQ magnet fully complies with the standards of the BEPCII-U project, demonstrating the software's effectiveness in practical applications.

Conclusion

The development and application of this software fill a crucial gap in China’s technology for producing superconducting magnets using direct winding methods, providing strong technical support for the development of accelerator engineering in China.
