A direct-detection X-ray CMOS image sensor with 500 μm thick high resistivity silicon

This paper reports recent results of a direct-detection X-ray CMOS image sensor for X-ray Free-Electron Laser (XFEL) experiments. The sensor incorporates the in-pixel dual gain circuitry by using Fully Depleted-Silicon-On-Insulator (FD-SOI) CMOS transistors located on top of the buried oxide (BOX) layer. Beneath of the BOX layer, high resistivity handle wafer made from floating zone method was ...

Evaluation of multifunctional targeted gold nanoparticles on X-ray attenuation in nasopharyngeal cancer cells by X- ray imaging

Introduction: Head-and-neck cancer is the sixth most common cancer worldwide with the number of cases consistently increasing in developing countries. Successful development of effective, safe and cost effective nanoprobes for head-and-neck cancer targeting imaging is a big challenge. This study is aimed to develop cysteamine-folate conjugated gold nanoparticles (F-Cys-AuNPs) a...

The new X-ray mapping: X-ray spectrum imaging above 100 kHz output count rate with the silicon drift detector.

Electron-excited X-ray mapping is a key operational mode of the scanning electron microscope (SEM) equipped with energy dispersive X-ray spectrometry (EDS). The popularity of X-ray mapping persists despite the significant time penalty due to the relatively low output count rates, typically less than 25 kHz, that can be processed with the conventional EDS. The silicon drift detector (SDD) uses t...

Lensless imaging using broadband X-ray sources

High-resolution X-ray imaging techniques using optical elements such as zone plates are widely used for viewing the internal structure of samples in exquisite detail. The resolution attainable is ultimately limited by the manufacturing tolerances for the optics. Combining ideas from crystallography and holography, this limit may be surpassed by the method of coherent diffractive imaging (CDI)1....

Target and projectile K x-ray production by 100, 160, and 200 MeV Nb collisions with thick solid targets

2014 Target and projectile K x-ray cross-sections produced in collisions of Nb projectiles with a series of targets (Zt = 6 68) are reported for energies of 100, 160 and 200 MeV. Various K-vacancy production theories were tested over this broad range including electron promotion with vacancy sharing (molecular model), direct excitation (ECPSSR theory), modified binary encounter approximation (B...
