White beam Laue transmission diffraction topography has been used to determine the curvature of a crystalline substrate, from which the stress in the overlaying coating is determined. A detailed analytical method has been developed which correlates the introduction of curvature to the substrate in two orthogonal directions with attendant changes in the dimensions of a given topographic reflecti...

We have developed a new in situ method to measure heating-induced distortions of the surface of the first monochromator crystal exposed to high-power white synchrotron radiation beam. The method is based on recording the image of a stationary grid of dots captured by a CCD camera as reflected from the surface of a crystal with and without a heat load. The three-dimensional surface profile (heat...

In this paper two imaging modes in a state-of-the-art scanning transmission electron microscope (STEM) are compared: conventional STEM with a convergent beam (referred to as nanoprobe) and STEM with a parallel beam (referred to as microprobe). The effect and influence of both modes with respect to their depth of field are investigated. Tomograms of a human white blood cell (hemophagocytes) are ...

We present the first experimental observation of modulation instability and spontaneous pattern formation with incoherent white light emitted from an incandescent light bulb. We show experimentally that modulation instability of white light propagating in a noninstantaneous self-focusing medium is a collective effect, where the entire temporal spectrum of the light beam becomes unstable at the ...

We report on a new method to form reconfigurable channel waveguides in lithium niobate crystals, based on a combination of low-dose O(3+) ion implantation and selective white light illumination. The fabricated structures show low loss as well as rather high resistivity against optical erasure with red or infrared light, while at the same time reconfiguration of the structures remains possible u...

Glucose cultures of Chlorella vulgaris were grown in white light, in monochromatic light, and in darkness. Difference spectra showed that all wavelengths resulted in increased pigmentation over the dark controls.Cells irradiated with the 600 mmu beam showed a much higher absorption in the blue end of the spectrum with respect to the red end than is normally found in absorption spectra of white-...

S. Bai, J. Gao, IHEP, Beijing, China P. Bambade, LAL, Orsay, France G. White, SLAC, USA Abstract The ATF2 project is the final focus system prototype for ILC and CLIC linear collider projects, with a purpose to reach a 37nm vertical beam size at the interaction point. In beam tuning towards the goal beam size, the presence of a tilt of the IP Shintake monitor fringe pattern with respect to the ...

Electrophoregrams with bands of green chlorophyll-containing protein complexes separated by native polyacrylamide gel electrophoresis (PAGE) are usually photographed in white light or scanned by a narrow beam of monochromatic light using densitometers. Present CCD cameras allow taking densitograms of a whole gel surface with many samples. However, commercial CCD imaging systems use mostly white...

We experimentally demonstrate that broad, tunable bandwidth of an optical ring cavity can be achieved by making use of the negative dispersion of the Kerr nonlinear refractive index in the three-level electromagnetically-induced transparency medium. For a given cavity field intensity, the white-light cavity condition can always be satisfied by choosing the appropriate coupling beam parameters. ...
