A 3.5 T superconducting multipole wiggler (SMPW) was designed, fabricated and measured at the National Synchrotron Radiation Research Center (NSRRC, Taiwan). The magnet was installed and operated in the Synchrotron Light Research Institute (SLRI, Thailand). The design concept of the SMPW improves on the operating experience of the superconducting magnet in NSRRC. The field strength could be generated by the NbTi coils and the magnetic arrays are immersed in a liquid helium (LHe) bath. A removable mapping chamber was developed to provides a room temperature environment for the magnetic field mapping in the cryostat. The magnet performance and field measurement results with the mapping chamber will be discussed in this report.
