Title: Performance of X-ray Beam lines at Superconducting Wavelength Shifter

Abstract

To fully utilize a hard X-ray source generated by a 5-Tesla superconducting wavelength shifter (SWLS) that shifts the critical energy of synchrotron spectrum from 2.1 to 7.5 keV, we have designed and constructed three hard X-ray beamlines, BL01A, BL01B, and BL0IC. BL01A is a white light beamline for phase-contrast X-ray image applications. The spatial resolution of phase-contrast X-ray image is 1 {mu}m. The photon flux can saturate a camera of 700-microns field-of-view within 10 ms. BL01B equipped with a double crystal monochromator (DCM) and a toroidal focusing mirror, which provides photon beams with energies from 5 to 20 keV, is adequate for scattering related experiments and hard X-ray microscopy. The energy-resolution {delta}E/E is 1 x 10-3. The photon flux is optimized to be 4.5 x 1011 photons s-1 with 200 mA ring current, which outcasts the flux of the wiggler beamline BL17B by 110 times at 15 keV. BL01C equipped with a DCM and both collimating and focusing mirrors, covering photon energies from 6 to 33 keV, is ideal for EXAFS and X-ray diffraction (XRD) experiments. The average photon flux is 3 x 1010 photons s-1 with 200 mA ring current. The energy-resolution is between 1.7 x 10-4 and 3.0more » x 10-4. In this article, we will present the measured performance of these beamlines.« less
