Summary:
NSLS-II is going to employ Damping Wigglers (DWs) not only for emittance reduction but also as broad band hard X-ray source. In-Vacuum Undulators (IVUs) with the minimum RMS phase error (< 2 degree) and possible cryo-capability are planned for X-ray planar device. Elliptically Polarized Undulators (EPUs) are envisioned for polarization controls. Due to the lack of hard X-ray flux from weak dipole magnet field (0.4 Tesla), three pole wigglers (3PWs) of the peak field over 1 Tesla will be mainly used by NSLS bending magnet beam line users. Magnetic designs and kick maps for dynamic aperture surveys were created using the latest version of Radia [1] for Mathematica 6 which we supported the development. There are other devices planned for the later stage of the project, such as quasi-periodic EPU, superconducting wiggler/undulator, and Cryo-Permanent Magnet Undulator (CPMU) with Praseodymium Iron Boron (PrFeB) magnets and textured Dysprosium poles. For R&D, Hybrid PrFeB arrays were planned to be assembled and field-measured at room temperature, liquid nitrogen and liquid helium temperature using our vertical test facility. We have also developed a specialized power supply for pulsed wire measurement.
