    Notes: The third-generation Advanced Photon Source will open up dramatic new opportunities for experiments requiring coherent x-rays, such as scanning x-ray microscopy, interferometry, and coherent scattering. We are building a beamline at the Advanced Photon Source to exploit the potential of coherent x-ray applications in the 1–4 keV energy region. A high brightness 5.5-cm-period undulator supplies the coherent x-rays. The beamline uses horizontally deflecting grazing-incidence optical elements to preserve the coherence of the undulator beam. The optics have multilayer coatings for operation at energies above 1.5 keV. This paper discusses the beamline design and its expected performance. © 1996 American Institute of Physics.

    Notes: A dedicated insertion-device beamline has been designed and is being constructed at the Advanced Photon Source (APS) for development of x-ray microfocusing- and coherence-based techniques and applications. Important parameters considered in this design include preservation of source brilliance and coherence, selectable transverse coherence length and energy bandwidth, high beam angular stability, high order harmonic suppression, quick x-ray energy scan, and accurate and stable x-ray energy. The overall design of this beamline layout and the major beamline components are described. The use of a horizontally deflecting mirror as the first optical component is one of the main features of this beamline design, and the resulting advantages are briefly discussed. © 1996 American Institute of Physics.

    On optimal contact cooling of high-heat-load x-ray mirrors : The 9th National conference on synchrotron radiation instrumentation (1996)

    Notes: Under appropriate conditions, optimal contact cooling provides an attractive cooling strategy for the design of high-heat-load mirrors. This approach avoids a number of problems and uncertainties inherent in the fabrication, assembly, and operation of internally cooled high-heat-load optics. In this paper, the optimal contact-cooling concept is described, its advantages, disadvantages, and limitations are pointed out, and various design aspects and options are discussed. Simple heuristic guidelines for the design of such substrates are provided. The mirror assembly consists of the polished substrate and two cooling blocks in contact with it. The mirror and cooling block dimensions as well as the location of the cooling blocks on the mirror, are optimized to provide a thermo-mechanically balanced system so that there are negligible tangential slope errors in the mirror without any bending mechanism. As an example, the design of a high-heat-load first mirror for the Advanced Photon Source (APS) is described. This mirror, which is 1.2 m long, is exposed to a total power of 2 kW with a uniform heat flux of 0.38W/mm2. This mirror is currently being fabricated. The concept of a thermo-mechanically balanced system can also be applicable to other high-heat-load optical components, such as monochromators. © 1996 American Institute of Physics.

    Design, fabrication, and evaluation of an internally cooled silicon carbide mirror : Papers from the 12th National Synchrotron Radiation Instrumentation Conference (2002)

    Notes: In this article, the design, fabrication, prepolish coating, and polishing of a reaction-bonded (RB) internally cooled silicon carbide (SiC) mirror is described. The mirror was developed from a mold of SiC powder in a near-net shape and then infused with silicon vapor to make a dense mirror substrate. The mirror surface was then rough polished, coated with a thin layer of SiC, and polished to a final fine finish. The design and manufacturing of this mirror—intended to be used as a multilayer substrate on a high-heat-load undulator beamline—are described, and data on the surface figure and finish are provided. This type of mirror can provide an attractive alternative to internally cooled silicon mirrors. Because the substrate is made in one piece, it avoids the frit or metal bonding that is usually necessary with silicon substrates. Advantages of RB SiC mirrors include lower cost and higher reliability. © 2002 American Institute of Physics.
