Title: Developments in time-resolved x-ray research at APS beamline 7ID

Abstract

The 7ID beamline of the Advanced Photon Source (APS) is dedicated to time-resolved research using x-ray imaging, scattering, and spectroscopy techniques. Time resolution is achieved via gated detectors and/or mechanical choppers in conjunction with the time structure of the x-ray beam. Three experimental hutches allow for a wide variety of experimental setups. Major areas of research include atomic, molecular, and optical physics; chemistry; condensed matter physics in the bulk, thin film, and surface regimes; and fluid-spray dynamics. Recent developments in facilities at 7ID include a high-power, high-repetition-rate picosecond laser to complement the 1 kHz ultrafast laser. For the ultrafast laser, a newly commissioned optical parametric amplifier provides pump wavelength from 0.2 to 15 µm with energy per pulse up to 200 µJ. A nanodiffraction station has also been commissioned, using Fresnel zone-plate optics to achieve a focused x-ray spot of 300 nm. This nanoprobe is not only used to spatially resolve the evolution of small features in samples after optical excitation, but also has been combined with an intense THz source to study material response under ultrafast electric fields.

  • The Sector 7 undulator beamline (7-ID) of the Advanced Photon Source (APS) is dedicated to time-resolved x-ray research and is capable of ultrafast measurements on the order of 100 ps. Beamline 7-ID has a laser laboratory featuring a Ti:Sapphire system (average power of 2.5 W, pulse duration <50 fs, repetition rate 1-5 kHz) that can be synchronized to the bunch pattern of the storage ring. The laser is deliverable to x-ray enclosures, which contain diffractometers, as well as motorized optical tables for table-top experiments. Beamline 7-ID has a single APS Undulator A and uses a diamond (111) double-crystal monochromator, providingmore » good energy resolution over a range of 6-24 keV. Available optics include Kirkpatrick-Baez (KB) mirrors to microfocus the x-ray beam. A variety of time-resolved diffraction and spectroscopy research is available at 7-ID, with experiments being done in the atomic, molecular, optical, chemistry, and solid state (bulk and surface) fields.« less

  • The Dynamic Compression Sector (DCS) beamline, a national user facility for time resolved dynamic compression science supported by the National Nuclear Security Administration (NNSA) of the Department of Energy (DOE), has recently completed construction and is being commissioned at Sector 35 of the Advanced Photon Source (APS) at Argonne National Laboratory (ANL). The beamline consists of a First Optics Enclosure (FOE) and four experimental enclosures. A Kirkpatrick–Baez focusing mirror system with 2.2 mrad incident angles in the FOE delivers pink beam to the experimental stations. A refocusing Kirkpatrick–Baez mirror system is situated in each of the two most downstream enclosures.more » Experiments can be conducted in either white, monochromatic, pink or monochromatic-reflected beam mode in any of the experimental stations by changing the position of two interlocked components in the FOE. The beamline Radiation Safety System (RSS) components have been designed to handle the continuous beam provided by two in-line revolver undulators with periods of 27 and 30 mm, at closed gap, 150 mA beam current, and passing through a power limiting aperture of 1.5 x 1.0 mm 2. A novel pink beam end station stop [1] is used to stop the continuous and focused pink beam which can achieve a peak heat flux of 105 kW/mm 2. Finally, a new millisecond shutter design [2] is used to deliver a quick pulse of beam to the sample, synchronized with the dynamic event, the microsecond shutter, and the storage ring clock.« less
  • The configuration and performance of the time-resolved dispersive XAFS (DXAFS) instrument, which has been constructed at the NW2A beamline of PF-AR (KEK), are presented. The DXAFS instrument is mainly composed of a polychromator part, a position control part for sample, and a linear detector part. The Bragg- and Laue-type polychromator crystal (Si(111) or Si(311)) is bent using the holder with fixed bending radius, in which the thermostated water is circulated to prevent the temperature change of crystal due to the heat load. The photodiode array (PDA) with and without phosphor screen is used as the linear X-ray detector, and themore » minimum exposure time is 2 ms for the 1024-element PDA. The phosphor screen on the PDA detector prevents the damage of the chip especially for high energy X-rays but the existence reduces the energy resolution because of the scattering of the visible light converted on the phosphor. The DXAFS instrument was applied to the mechanistic study of the reduction processes of Cu supported on MFI zeolite, and the intermediate Cu(I) states have been successfully observed during the reduction from Cu(II) to Cu(0)« less
