A 3.3-cm period Nd-Fe-B hybrid undulator has been designed and successfully operated in the Cornell Electron Storage Ring (CESR). This 2-m-long, 123-pole insertion device is a prototype of one undulators planned for Advanced Photon Source. In dedicated operation, produced expected brightness at 5.437 GeV with fundamental x-ray energy ranging from 4.3 to 7.9 keV corresponding change gap 1.5 2.8 cm.
