Experiences with CCD detectors on a home X-ray source.
Charged-coupled device (CCD) detectors have been widely accepted as detectors for collecting X-ray diffraction images. The CCD detector offers a sensitive detection system well suited for diffraction analysis and, compared with other detectors on the market, a relatively rapid system for read-out of the collected image. The two predominant markets for the CCD detector have been those in which r...
متن کاملExtending The Methodology Of X-ray Crystallography To Allow X-ray Microscopy Without X-ray Optics
We demonstrate that the soft X-ray diffraction pattern from a micron-size noncrystalline specimen can be recorded and inverted to form a high-resolution image. The phase problem is overcome by oversampling the diffraction pattern. The image is obtained using an iterative algorithm. The technique provides a method for X-ray microscopy requiring no highresolution X-ray optical elements or detecto...
متن کاملHigh Repetition Rate X-ray Preionization Source
discharges. These photons can be generated by stopping 7OkeV electrons by a target made of high z material like tungsten or tantalum. In this contribution we describe the performance of an X-ray generator employing a corona plasma cathode [1]. Electrons can easily be extracted from a plasma on the surface of a dielectric. The plasma is generated by accelerating electrons, emitted from sharp edg...
متن کاملX-ray Source Populations in Galaxies
Today’s sensitive, high-resolution X-ray observations allow the study of populations of X-ray sources, in the luminosity range of Galactic X-ray binaries, in galaxies as distant as 20-30Mpc. The traditional astronomical tools of photometric diagrams and luminosity functions are now applied to these populations, providing a direct probe of the evolved binary component of different stellar popula...
متن کاملQuasi-monochromatic field-emission x-ray source.
By favoring the L-peak emission over the bremsstrahlung part, direct quasi-monochromatic soft x-ray emission has been obtained with a field emission (FE) x-ray source. The electron impact x-ray setup uses an arrayed cathode of carbon nanopearl FE tips as a stable cold electron source within a vacuum of 10(-6)-10(-7) Torr. The high brightness of the FE e-beam coupled with the array structure of ...
