  1. SAC presentation, Barcelona 21st February 2005 Proposal for a beamline on Non Crystalline Diffraction for Life and Material Sciences with Modular Microfocus Option on ALBA Presented on behalf of the working group by: T.A. Ezquerra Instituto de Estructura de la Materia, CSIC Serrano 119, Madrid 28006

  2. Outline • What? • Why? • Who?

  3. Small Angle X-ray Scattering Wide Angle X-ray Scattering Microfocus Option What? Non Crystalline Diffraction Beamline Requirements Brilliance: 1017-1018 photons/s/(mrad)2/(mm)2 Energy range: Continuous from 0.2 nm (6 keV) to 0.07 nm (20 keV) optimized for 0.1 nm (12.4 keV). Photon flux: 1012 Ph/s Band Pass: 10-4 With standard focusing Beam size at sample/detector: 10mm (V), 150 mm (H) Divergence at sample/detector: 0.02mrad(V), 0.04 mrad (H) With microfocus Beam size at sample/detector < 5mm diameter. Divergence at sample/detector:  0.05 mrad Positional stability: 1 % RMS during 1-10 seconds

  4. What? Tentative layout ID Monochromator Mirror Microfocus optics Pin-hole collimation (5 and 10 mm collimators). Kirkpatrick-Baez mirror. ≤ 1 mm Fresnel lenses (0.1-0.5 mm with a 109 ph/s flux). Beryllium Compound Refractive Lenses. Toroidal focusing mirror (vertical and horizontal focusing). A double crystal Si (111) monochromator or Multilayer Vacuum undulator will be required due to the higher flux and to the lower divergence

  5. WAXS detector • A fast single photon counting area detector • area approximately 20 x 20 cm2, large dynamic range • maximum count rate of 10 x 106 counts/sec • spatial resolution of 200 – 250 mm • efficiency between 60 – 80 % What? Tentative layout SAXS detector • CCD Area detector for SAXS and WAXS (MAR CCD, diameter ~ 300 mm) • Fast linear one dimensional detectors • (1-D microstrip gas chamber curved arrangement) • (1-D wire detectors) diffractometry.

  6. Engagement of Users!! What? Tentative layout • Scanning set-up: - x/y translation stage • Micro-hexapod: rotation range ±5º with 2 mrad increment • Video microscope. • Microgoniometer: rotating arm • Temperature furnaces. • High pressure cells. • Heating/cooling stage for DSC • Heating/cooling shear cell. • Tensile stretching machine. • Magnetic field.
