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...
After less than two years of commissioning the FERMI@Elettra free electron laser is now entering into operation phase and providing light to first user experiments. To reach final ambitious goals high power coherent pulses with fundamental wavelengths down 4 nm, system will need further studies additional time in 2011 when fine tuning major systems such as gun main accelerator take place. Nevertheless, FERMI already able provide unique characteristics allowing Users perform experiments not...
With the 3 GeV electron beam energy for National Synchrotron Light Source II (NSLS-II) ring, only superconducting wigglers (SCW) producing greater than 4T peak field can cover photon range of 20 keV and 200 with sufficient number photons. The High Engineering X-ray (HEX) Diffraction beamline, which is primarily funded by New York State Energy Research Development Authority (NYSERDA) NSLS-II, will be equipped a 1.2m-long SCW 70 mm period length 4.3 T on-axis field. This free from use liquid...
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...
The National Synchrotron Light Source II (NSLS-II) is preparing for a major upgrade based on new lattice concept, known as "Complex Bend," to replace its existing Double Bend Achromat (DBA). This novel will use high-gradient permanent magnet quadrupoles (PMQs) with small apertures in the range of 16-22 mm. A prototype complex bend branch PMQs has been installed NSLS-II linac evaluate lattice's performance. An accurate and precise magnetic measurement system required field harmonic...

A quasi periodic elliptical undulator (QP-EPU105) has been recently put in operation at the Electron Spectro Microscopy beamline NSLS-II. Commissioning results pertaining to its initial characterization are presented. The spectral and angular distributions of light have probed compared with emission calculations based on measured magnetic field. polarization produced parallel anti-parallel modes is also quantitatively analyzed.
