  A superconducting multipole wiggler (SMPW) was fabricated at the National Synchrotron Radiation Research Center (NSRRC) and was installed in the Synchrotron Light Research Institute (SLRI). A 3.5 T 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, made from thin stainless steel sheets, was developed to allow field mapping in the narrow aperture of the SMPW. The mapping chamber provides a room temperature environment for the magnetic field mapping and enables an easier field scan in the cryostat. The design for the mapping chamber includes a blockage of heat transfer from room temperature to the LHe bath and is strong enough to resist deformations during evacuation. The mechanical design, strain simulation, thermal simulation, dummy test and measurement results with the mapping chamber will be discussed in this paper.
