A dedicated compression device for high resolution X-ray tomography of compressed gas diffusion layers.

Three-dimensional Study of Compressed Gas Diffusion Layers using Synchrotron X-ray Imaging

Real-time, high-resolution x-ray diffraction measurements on shocked crystals at a synchrotron facility.

The Advanced Photon Source (APS) at Argonne National Laboratory was used to obtain real-time, high-resolution x-ray diffraction measurements to determine the microscopic response of shock-compressed single crystals. Disk shaped samples were subjected to plane shock wave compression by impacting them with half-inch diameter, flat-faced projectiles. The projectiles were accelerated to velocities ...

Assessment of X-Ray Crosstalk in a Computed Tomography Scanner with Small Detector Elements Using Monte Carlo Method

Introduction: Crosstalk is a leakage of X-ray or light produced in a matrix of X-ray detectors or array of photodiodes in one element to other elements affecting on image contrast and spatial resolution. In this study, we assessed X-ray crosstalk in a computed tomography (CT) scanner with small detector elements to estimate the effect of various parameters such as X-ray tube voltage, detector e...

EFFECTS OF TEMPERATURE AND AL-CONCENTRATION ON FORMATION MECHANISM OF AN ALUMINIDE COATING APPLIED ON SUPER ALLOY IN738LC THROUGH A SINGLE-STEP HIGH ACTIVITYGAS DIFFUSION PROCESS

Abstract: activity gas diffusion process has been investigated in this research. Effects of coating temperature and aluminumconcentration in powder mixture on formation mechanism were studied using optical and scanning electronmicroscopes, EDS and X-ray diffraction (XRD) techniques. For this purpose two different packs containing 1 and 2wt% aluminum powder, were used for coating the samples at ...

Design of Small Animal Computed Tomography Imaging for in vitro and in vivo Studies

Introduction: Mini Computed Tomography (mini-CT) was suggested in biomedical research to investigate tissues and small animals. We present designed and built a mini x-ray computed tomography (mini-CT) for small animals as well as industrial component imaging. Materials and Methods: The system used in this study includes a X-ray tube 20kV to 160kV and a flat pa...
