13A1　SW60 - X-ray Scattering

Abstract

TLS Beamline 13A (BL13A1) is an insertion-device beamline designed chiefly for studying lamellar structure. As a side-branch beamline, BL13A1 has been designed to fully utilize the sideway output of the superconducting multipole wiggler (smpw) and could provide hard x-ray photons up to 6 × 10¹⁰ per second at 12 keV. An asymmetric-cut curved crystal monochromater (ACCM) has been employed to offer monochromatic-beam with energy resolution (E/∆E) ∼ 700. A four-circle Huber diffractometer with a scintillation detector is placed in the experimental hutch and provide the capability for high resolution wide-range x-ray diraction experiments, such as x-ray diraction (XRD), x-ray reectivity (XRR), and lamellar x-ray diraction. Another two-dimension detector assembly is also available. A Rayonix SX165 which is a round CCD detector with 165 mm diameter active area is used to collect 2D x-ray scattering pattern with avalible q range from 0.05 Å⁻¹to 2.7 Å⁻¹. For different experiment requirements, several setups have been designed : a regular sample rod for general XRD and XRR, a heatable stage with temperature range from room temperature to 250 ◦C, a heatable transmission chamber for liquid and solution, and a chamber with temperature and humidity control for bio-membrane samples.
