Monte Carlo simulation analysis of X-ray density logging shields
He jishuBackgroundThe use of controlled X-ray sources instead of 137Cs radioactive sources in density logging has become a new trend. The intensity of the X-ray source is substantially influenced by the high voltage on the target substrate, and the density ...

View synthesis for kinetic depth X-ray imaging
, 2012 This thesis reports the development and analysis of feature based synthesis of transmission X-ray images. The synthetic imagery is formed through matching and morphing or warping line-scan format images produced by a novel multi-view X-ray machine.

Characterization of x-ray detectors in the MIT x-ray polarimetry beamline
X-Ray, Optical, and Infrared Detectors for Astronomy XIThe MIT X-ray Polarimetry Beamline is a facility that we developed for testing components for possible use in X-ray polarimetry. Over the past few years, we have demonstrated that the X-ray source can generate nearly 100% polarized X-rays at various energies from 183 eV (Boron K$α$) to 705 eV (Fe L$α$) using a laterally graded multilayer coated mirror (
