In situ two-dimensional imaging quick-scanning XAFS with pixel array detector
نویسندگان
چکیده
Quick-scanning X-ray absorption fine structure (XAFS) measurements were performed in transmission mode using a PILATUS 100K pixel array detector (PAD). The method can display a two-dimensional image for a large area of the order of a centimetre with a spatial resolution of 0.2 mm at each energy point in the XAFS spectrum. The time resolution of the quick-scanning method ranged from 10 s to 1 min per spectrum depending on the energy range. The PAD has a wide dynamic range and low noise, so the obtained spectra have a good signal-to-noise ratio.

Simulation of a Neutron Detector for Real Time Imaging Applications
Monte Carlo Method is used to simulate a double layer gadolinium-amorphous silicon thermal neutron detector. The detector fabricated in pixel array configuration has various applications including neutron imaging. According to the simulation results, a detector consisting of a gadolinium (Gd) film with thickness of 2-4 ~m, sandwiched properly with two layers of sufficiently thick (-30 ?µm) hydr...
متن کامل A novel approach to automatic position calibration for pixelated crystals in gamma imaging
Introduction: The position estimation in gamma detection system will have constant misplacements which can be corrected in the calibration procedure. In the pixelated crystal uniformly irradiation of detector will produce irregular shape due to position estimation errors. This image is called flood field image and is used to calibrate the position estimation. In this work we pr...

Flat Panel Illustration In 2000, a large array A-Si flat panel EPID detector was installed (AL-7) on one of the PRIMUS accelerator at UCSF to allow for a comparison of performance. During the development period of MVCBCT, the introduction in 2004 of a new flat panel (AG-9) better optimized for high energy photons showed a several fold increase in sensitivity, allowing the routine acquisition of...
متن کاملRESOLUTION PERFORMANCE IMPROVEMENTS IN STARING IMAGING SYSTEMS USING MICRO - SCANNING AND A RETICULATED , SELECTABLE FILL FACTOR InSb FPA
As staring focal plane array (FPA) detectors continue to mature, FPA based IR imaging systems are available in more compact packages that are lighter and consume less power than first or second generation scanning IR sensor packages. However, standard IR analysis models indicate that staring FPA based cameras, while having excellent sensitivity, will have reduced resolution when compared to sca...
