2024-06-24 Research and development of a 0.5-m-long helical superconducting undulator prototype doi:10.57760/sciencedb.j00186.00158 en The helical undulator is in high demand in synchrotron radiation facilities for circular polarization generation. Owing to the higher field strength provided by the superconducting undulator compared to the conventional permanent-magnet undulator, greater research efforts should be directed towards this area. The helical superconducting undulator holds great potential in synchrotron radiation facilities, especially in low-energy storage rings that seek circularly polarized radiation with the highest possible radiation flux. Following the successful development of planar superconducting undulators, the Institute of High-Energy Physics conducted research and development for the helical superconducting undulator. A 0.5−m-long Delta-type prototype superconducting undulator was developed and tested. Detailed information on the design, fabrication, and cryogenic testing of the prototype are presented and discussed.
