主　　题：3W1 Superconducting Magnet 

摘      要：Introduction The superconducting wiggler magnet named as 3W1 is the key device for the test facility for the High Energy Photon Source(HEPS).The magnet structure is 1430 mm long with a gap of 68 mm,and the designed peak field is 2.6 *** main magnet part is comprised by 28 main coils and 4 correction coils at both *** to the large gap and high field,the manufacturing process is extremely *** During R&D,the problems of coil winding,impregnation,pre-stress evaluation and quench risk control were solved by optimizing the *** coils were divided into groups to complete the cryogenic test,and the qualified coils were selected to complete the assembly of the *** The bare magnet has been tested with liquid helium bath in April 2018 in IHEP,and the loading current reached up to 345 A resulting in the expected 2.61 *** this paper,the technology about the coil winding,impregnation,assembling and test is presented in detail.
