Synchrotron X-ray analysis of the Sn electromigration behavior and whisker growth in a Blech structure using nano-X-ray fluorescence microscopy white beam Laue nanodiffraction was conducted. depletion at cathode whisker/extrusion formation anode were characterized in-situ, results obeyed kinetics. This scenario gradually decayed because counterbalance between electron wind force back stress. Wh...

2014 Modern electron (positron) storage rings are able to emit very intense X-ray radiation with a continuous spectrum extending to 0.1 A, from bending magnets and insertion devices (wavelength shifters and multipole wigglers). It can be used directly for white beam experiments and/or for monochromatic beam experiments with wavelength chosen at will from the continuous spectrum. Another type of...

In this work, we investigate the effect of air convection on laser-beam pointing noise essential for the long trace profiler (LTP). We describe this pointing error with noise power density (NPD) frequency distributions. It is shown that the NPD spectra due to air convection have a very characteristic form. In the range of frequencies from ~0.05 Hz to ~0.5 Hz, the spectra can be modeled with an ...

BACKGROUND Chordoma is a rare invasive bone tumor that may occur anywhere along the neuraxis. A total of three primary histological varieties have been identified: conventional, chondroid, and dedifferentiated. CASE PRESENTATION We report a case of an 8-year-old white girl who presented with conventional chordoma, was treated with surgical resection and mixed proton and photon beam therapy, a...

The Research Center for Nuclear Physics (RCNP) cyclotron cascade system has been operated to provide high quality beams for various experiments. In order to increase the physics research opportunities, the Azimuthally Varying Field (AVF) cyclotron facility was upgraded recently. A flat-topping system and an 18-GHz superconducting Electron Cyclotron Resonance (ECR) ion source were introduced to ...

We consider the propagation of temporally pulsed electromagnetic waves in a threedimensional random medium. The main objective is to derive effective white-noise paraxial equations from Maxwell’s equations. We address the scaling regime in which (1) the carrier wavelength is small compared to the incident beam radius, which itself is small compared to the propagation distance; (2) the correlati...

INTRODUCTION Radix entomolaris presents with an unusual morphology and is a rare occurrence. It is mainly observed in mandibular first molars. The incidence varies in different populations but it is far from common. This is especially true for mandibular second molars which possess the lowest prevalence. Some case reports have shown the presence of this finding in mandibular second molars; howe...

A description is given of multiple-beam interference precision methods for studying the surface topography and internal structural features of thin slips of mica. Three methods are described involving (a) new white light multiple-beam interference fringes, called here ‘fringes of equal chromatic order’, (b) an adaptation of monochromatic multiple-beam Fizeau fringes, (c) monochromatic multiple-...

Two d i f f e r e m kynthetic diamond-based Xray transmitting beam position monitor (XBPM) prototypes have been studied with an undulator white beam at the European Synchrotron Radiation Facility (ESRF) ID-6 beamline. Of particular interest was the possibility of designing an integral window and filtedphoton beam position monitor for the Advanced Photon Source (APS) high heat flux insertion dev...

One ingredient in an empirical birthrate estimate for pulsar binaries is the fraction of sky subtended by the pulsar beam: the pulsar beaming fraction. This fraction depends on both the pulsar’s opening angle and the misalignment angle between its spin and magnetic axes. The current estimates for pulsar binary birthrates are based on an average value of beaming fractions for only two pulsars, i...
