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...
This paper reports recent lattice characterization results obtained at the National Synchrotron Light Source II (NSLS-II) storage ring, conducted without reliance on a model. A pair of beam position monitors (BPMs) with bunch-by-bunch (B$\times$B) resolution, were recently installed in section ring free magnetic fields. The new BPM measured beam, or bunch's transverse Poincar\'e map precisely after was excited. Linear one-turn-matrices (OTM) then derived, and from these, 4-dimensional...
