X - Ray Imaging using a Pixel GaAs Detector
The electrical characteristics,charge collection eeciency and energy resolution of a GaAs detector made out of LEC material have been studied. A matrix of 36 square pixels was deposited on a 70 m thick crystal; each pixel had an area of 200x200 m 2 with 20 m spacing between adjacent pixels. This detector showed a charge collection eeciency uniformity among the pixels better than 88% when expose...
متن کاملPixel array detector for X-ray free electron laser experiments
X-ray free electron lasers (XFELs) promise to revolutionize X-ray science with extremely high peak brilliances and femtosecond X-ray pulses. This will require novel detectors to fully realize the potential of these new sources. There are many current detector development projects aimed at the many challenges of meeting the XFEL requirements [1,2]. This paper describes a pixel array detector (PA...
متن کاملFast X-ray reflectivity measurements using an X-ray pixel area detector at the DiffAbs beamline, Synchrotron SOLEIL.
This paper describes a method for rapid measurements of the specular X-ray reflectivity signal using an area detector and a monochromatic, well collimated X-ray beam (divergence below 0.01°), combined with a continuous data acquisition mode during the angular movements of the sample and detector. In addition to the total integrated (and background-corrected) reflectivity signal, this approach y...
متن کاملDevelopment of an X-ray pixel detector with multi-port charge-coupled device for X-ray free-electron laser experiments.
This paper presents development of an X-ray pixel detector with a multi-port charge-coupled device (MPCCD) for X-ray Free-Electron laser experiments. The fabrication process of the CCD was selected based on the X-ray radiation hardness against the estimated annual dose of 1.6 × 10(14) photon/mm(2). The sensor device was optimized by maximizing the full well capacity as high as 5 Me- within 50 μ...
متن کاملX-ray tests of a Pixel Array Detector for coherent x-ray imaging at the Linac Coherent Light Source
Test results are presented of a pixel array detector (PAD) developed for x-ray imaging at the Stanford Linear Coherent Light Source (LCLS). The basic module of the PAD consists of two bump-bonded chips: a reverse-biased silicon diode chip of 185× 194 pixels, each of which is coupled by bump-bonds to a charge integrating CMOS ASIC with digitization in each pixel. The LCLS experiment requires a h...
