View synthesis for depth from motion 3D x-ray imaging. [PDF]

, 2009
The depth from motion or kinetic depth X-ray imaging (KDEX) technique is designed to enhance the luggage screening at airport checkpoints. The technique requires multiple views of the luggage to be obtained from an arrangement of linear X-ray detector ...

320x240 GaAs pixel detectors with improved X-ray imaging quality

, 2001
We report on gain and offset corrections for GaAs X-ray pixel detectors, which were hybridised to silicon CMOS readout integrated circuits (ROICs). The whole detector array contains 320 x 240 square-shaped pixels with a pitch of 38 mum.

Semiconductor X-ray detectors

, 2014
Identifying and measuring the elemental x-rays released when materials are examined with particles (electrons, protons, alpha particles, etc.) or photons (x-rays and gamma rays) is still considered to be the primary analytical technique for routine and ...

Low-noise CMOS Charge Preamplifier for X-ray Spectroscopy Detectors

, 2010
The development of radiation detectors for high-resolution high-rate X-ray spectroscopy is strictly related to the continuous improvement of the performances of the related front-end readout electronics.

An X-ray Polarimeter for HXMT Mission [PDF]

, 2007
The development of micropixel gas detectors, capable to image tracks produced in a gas by photoelectrons, makes possible to perform polarimetry of X-ray celestial sources in the focus of grazing incidence X-ray telescopes.

Heteroepitaxial passivation of Cs2AgBiBr6 wafers with suppressed ionic migration for X-ray imaging

Nature Communications, 2019
Ionic migration degrades not only the characteristics of halide perovskite solar cells, but also those of perovskite X-ray detectors. Here Yang et al.

The effect of proton damage on the X-ray spectral response of MOS CCDs for the swift X-ray telescope [PDF]

, 2002
The effect of non-ionising energy loss(NIEL) of protons in charge-coupled devices is to displace silicon atoms and any dopant materials present from their lattice positions to form lattice defects which in turn can trap electrons [1].
