B16-Test Beamline	Synchrotron Characterisation of Non-Uniformities in a Small Pixel Cadmium Zinc Telluride Imaging Detector M. C. Veale , S. J. Bell , D. D. Duarte , A. Schneider , P. Seller , M. D. Wilson , V. Kachkanov , K. J. S. Sawhney Nuclear Instruments And Methods In Physics Research Section A: Accelerators, Spectrometers, Detectors And Associated Equipment DOI: 10.1016/j.nima.2013.07.054 Show Abstract ▼ Abstract: A small pixel cadmium zinc telluride detector has been fabricated, assembled and tested at the Rutherford Appleton Laboratory. The detector consists of 74×74 pixels on a 250 ?m pitch with a 50 ?m spacing. Flat field irradiations with an 241Am ?-ray source have demonstrated that there are significant variations in the number of counts detected by each pixel as well as large differences in the FWHM of the X-ray photo-peak. A 10×10 ?m microbeam of 20 keV X-rays has been used to characterise these non-uniformities. These measurements have shown that variations in the counting and spectroscopic performance of individual pixels are due to the presence of a non-uniform electric field within the detector	Jul 2013
B16-Test Beamline Optics	Germanium and silicon kinoform focusing lenses for hard xrays L. Alianelli , K. J. S. Sawhney , M. K. Tiwari , I. Dolbnya , R. Stevens , D. Jenkins , I. Loader , M. Wilson , A. Malik 9th International Conference on X-Ray Microscopy DOI: 10.1088/1742-6596/186/1/012062 Diamond Proposal Number(s): [192] Show Abstract ▼ Abstract: Progress in synchrotron radiation instrumentation and successful fabrication of novel x-ray optics enables probing the matter at micro- and nano-scales from virtually any sciences from biomedical, environmental to material sciences. In-line, compact focusing optics, based on refraction, are designed and fabricated for use in hard and very hard x-ray beamlines at Diamond. The first test results at a Diamond beamline, using micro-focusing silicon and germanium lenses, are discussed in this paper.	Oct 2009

Controls	Diamond Personnel Safety System M. C. Wilson , K. A. R. Baker , E. V. Buckley , M. T. Heron , J. R. Alexander ICALEPCS 2003 Show Abstract ▼ Abstract: Diamond is a new synchrotron light source currently being designed and constructed in the UK. The Diamond personnel safety system will protect people from the hazards associated with the accelerators and photon beamlines. The choice of technology and conceptual design of the Diamond Personnel Safety System (PSS) are presented, together with planned analysis methods that will provide a quantitative measure of the overall reliability of the PSS.
