This book was released on 1988 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earlier experimentation was completed on the development of a position sensitive x-ray detector based on Charge Couple Device (CCD) technology. To create a system that would adequately discriminate x-ray energy levels, the noise level of the CCD readout system needed to be minimized and the ability of the CCD itself to fully collect the x-ray produced charge needed to be improved. This report summarizes the efforts made to improve the test system by both optimizing its readout mechanisms and by optimizing the CCD itself. Experimentation was done to determine the capability of the EEV Standard (P86223) CCD (3 um depletion region) and the experimental EEV High Resistivity (P8600HR) CCD (30 um depletion region). System characteristics such as system noise and charge transfer efficiency were analyzed and the system modified. Once the system performance had been pushed close to its limits, x-ray tests were performed.

Download or read book Synthetic Diamond based Position sensitive Photoconductive Detector Development for the Advanced Photon Source written by and published by . This book was released on 1997 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: A novel x-ray beam position detection device that we call a position sensitive photoconductive detector (PSPCD) is designed to have synthetic diamond as its substrate material. We proved that it is feasible to use synthetic diamond to make a hard x-ray position sensitive detector based on the photoconductivity principle and that acts as a solid state ion chamber. Experiments on different PSPCD samples using synthetic diamond with high heat flux white undulatory beam, as well as with monochromatic hard x-ray beams, have been done at the Advanced Photon Source. Recent test results with the PSPCD in quadrant configuration as an x-ray beam position monitor and in a multipixel array as an x-ray beam profile are presented in this paper.

This book was released on 1999 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: A position-sensitive photoconductive detector (PSPCD) using insulating-type CVD diamond as its substrate material has been developed at the Advanced Photon Source (APS). Several different configurations, including a quadrant pattern for a x-ray-transmitting beam position monitor (TBPM) and 1-D and 2-D arrays for PSPCD beam profilers, have been developed. Tests on different PSPCD devices with high-heat-flux undulator white x-ray beam, as well as with gamma-ray beams from 6°Co sources have been done at the APS and National Institute of Standards and Technology (NIST). It was proven that the insulating-type CVD diamond can be used to make a hard x-ray and gamma-ray position-sensitive detector that acts as a solid-state ion chamber. These detectors are based on the photoconductivity principle. A total of eleven of these TBPMs have been installed on the APS front ends for commissioning use. The linear array PSPCD beam profiler has been routinely used for direct measurements of the undulator white beam profile. More tests with hard x-rays and gamma rays are planned for the CVD-diamond 2-D imaging PSPCD. Potential applications include a high-dose-rate beam profiler for fourth-generation synchrotrons radiation facilities, such as free-electron lasers.

Download or read book Development of Ta based Superconducting Tunnel Junction X ray Detectors for Fluorescence XAS written by and published by . This book was released on 2009 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: We are developing superconducting tunnel junction (STJ) soft X-ray detectors for chemical analysis of dilute samples by fluorescence-detected X-ray absorption spectroscopy (XAS). Our 36-pixel Nb-based STJ spectrometer covers a solid angle [Omega]/4[pi] ≈ 10−3, offers an energy resolution of ≈10-20 eV FWHM for energies up to ≈1 keV, and can be operated at total count rates of ≈106 counts/s. For increased quantum efficiency and cleaner response function, we have now started the development of Ta-based STJ detector arrays. Initial devices modeled after our Nb-based STJs have an energy resolution below 10 eV FWHM for X-ray energies below 1 keV, and pulse rise time discrimination can be used to improve their response function for energies up to several keV. We discuss the performance of the Ta-STJs and outline steps towards the next-generation of large STJ detector arrays with higher sensitivity.
