Enhanced colour encoding of materials discrimination information for multiple view dual-energy x-ray imaging

, 2009
This thesis reports an investigation into dual-energy X-ray discrimination techniques. These techniques are designed to provide colour-coded materials discrimination information in a sequence of perspective images exhibiting sequential parallax.

Ultra-thin 3D silicon sensors for neutron detection

, 2012
We present a novel neutron detector based on an ultra-thin 3D silicon sensor with a sensitive volume only 10 µm thick. This ultra-thin active volume allows a high gamma-ray rejection, a key requirement in order to discriminate the signal coming from the ...

Synthesis and coordination chemistry of a diphospha-tetrathia macrocycle, 1,10-diphenyl-1,10-diphospha-4,7,13,16-tetrathiacyclooctadecane [PDF]

, 2004
Reaction of 1,2-dichloroethane with PhP(CH2CH2SH)(2) and caesium carbonate affords 1,10-diphenyl-1,10-diphospha-4,7,13,16-tetrathiacyclooctadecane (18P2S4) in high yield (ca. 90%).

Phase-resolved Deadtime of the Crab Pulsar Using IXPE Data

The Astrophysical Journal
After receiving an X-ray photon, an X-ray detector is not operational for a duration known as deadtime. It is detector specific and its effect on the data depends upon the luminosity of the source.

Ultra high energy gamma ray point sources and cosmic ray anisotropy [PDF]

, 1994
The experimental set-up at the Baksan Air Shower Array, used to detect air showers above ~0.2xl0(^14)eV, is described. An estimation of the angular resolution using the cosmic ray shadow of the Sun and the Moon gives a value of ~2.5˚ which is consistent ...

Micro- and nanostructure of human teeth : a synchrotron radiation-based X-ray study [PDF]

, 2014
The anisotropic composite nature of human teeth guarantees their function for decades under high mechanical loads and adverse chemical conditions. Even more so since only marginal remodelling and repair mechanisms take place in adult teeth.
