The National Synchrotron Light Source-II (NSLS-II) project is now in the final stage of construction. Linac, Booster synchrotron, and Storage Ring magnets girder assemblies have been installed. first damping wiggler has delivered its field characteristics are carefully measured. A Three Pole Wiggler (3PW) Apple-II type elliptically polarizing undulators (EPUs) fabricated by vendors. Two 3.0m long in-vacuum (IVUs) one 1.5m IVU almost complete waiting for factory acceptance tests. One...
The NSLS-II storage ring completed commissioning in 2014 and all project-beamline IDs have also been commissioned. As of February 2015, six beamlines are about to finish commissioning. By the end is expected store 300 mA with top-up injection capability 500 a second superconducting RF cavity installed following year. design principle employ low-field BMs simultaneously install high-field wigglers non-dispersive straights reduce horizontal emittance. more installed, smaller electron beam...
The High energy Engineering X-ray (HEX) diffraction beamline at the National Synchrotron Light Source II (NSLS-II) Brookhaven Lab (BNL) is first high-energy capable of reaching 200 keV for a monochromatic beam. With 3 GeV electron beam NSLS-II ring, only superconducting wiggler (SCW) producing greater than 4 T peak field can cover these ranges with sufficient number photons. 1.2 m-long HEX-SCW has period length 70 mm and strength on-axis 4.3 T. It utilizes no liquid helium, vertical aperture...
The National Synchrotron Light Source II (NSLS-II) is a state of the art 3 GeV third generation light source at Brookhaven Laboratory. During spring/ summer 2014, storage ring was commissioned up to 50 mA without insertion devices. In fall we began commissioning project beamlines, which included seven devices on six ID ports. Beamlines IXS, HXN, CSX-1, CSX-2, CHX, SRX, and XPD-1 consist elliptically polarized undulator (EPU), damping wigglers (DW) in-vacuum undulators (IVU) covering from VUV...
National Synchrotron Light Source-II (NSLS-II) is the latest storage ring of 3 GeV energy with horizontal emittance electron beam being 0.9 nm.rad. Nine In-Vacuum Undulators (IVUs) are utilized at NSLS-II as February 2016. All IVUs have a unique side window derived from experience CHESS facility in Cornell University. An R&D activity called “Vacuum Seal Test” was conducted to ensure viability aluminum wire seal. Another develop measurement system for Cryogenic Permanent Magnet Undulator...

National Synchrotron Light Source-II (NSLS-II) is the latest storage ring of 3 GeV energy at Brookhaven Laboratory (BNL). The horizontal emittance electron beam with currently installed six damping wigglers 0.9 nm.rad, which could be further reduced to 0.5 nm.rad more insertion devices (IDs). With only one RF cavity current restricted 200 mA. Five hundred mA operation envisaged for next year an addition second cavity. Six (plus two branches) beamlines have been commissioned in initial phase...
