摘要
National Synchrotron Light Source-II (NSLS-II) will be a medium energy storage ring of 3 GeV electron beam energy with sub-nm rad horizontal emittance and top-off capability at 500 mA. Damping wigglers will be used not only to reduce the beam emittance but also used as broadband sources for users. Cryo-Permanent Magnet Undulators (CPMUs) are considered for hard X-ray linear device, and permanent magnet-based elliptically polarized undulators (EPUs) for variable polarization devices for soft X-ray. Six Tesla superconducting wiggler with minimal fan angle will be installed in the second phase as well as quasi-periodic EPU for VUV and possibly high-temperature superconducting undulator. R&D plans have been established to pursue the performance enhancement of the baseline devices and to design new types of insertion devices. A new insertion device development laboratory will also be established.
