Matthew Soman (Open University)04/09/2012, 09:00X-ray imaging applications - Material ScienceORALThe Super Advanced X-ray Emission Spectrometer (SAXES) at the Swiss Light Source contains a high resolution Charge Coupled Device (CCD) based camera used for Resonant Inelastic X-ray Scattering (RIXS) [1]. Using the current CCD based camera system, the energy-dispersive spectrometer has an energy resolution (E/ΔE) of approximately 12000 at 930 eV [2]. A recent study [3] predicted that through...Go to contribution page

Prof. Shunji Kishimoto (High Energy Accelerator Research Organization)04/09/2012, 09:20X-ray imaging applications - Material ScienceORALWe have developed a silicon avalanche-photodiode (Si-APD) array detector for time-resolved measurements using pulsed synchrotron X-rays. The Si-APD detector had 64 pixels of a linear array, where the pixel size was 100 μm by 200 μm with a 50-μm gap between pixels and a depleted thickness was 10 μm. The detector system was equipped with 64-channel front-end ASICs, FPGAs and SiTCP (a network...Go to contribution page

Dionisio Doering (LBNL)04/09/2012, 09:40X-ray imaging applications - Material ScienceORALAt the Advanced Light Source (ALS) at Lawrence Berkeley National Laboratory (LBNL) several experiments are performed in the soft X-ray regime with energy ranging from a few hundred to a few thousand electron volts (eV). In such applications, back-illuminated, direct detection in silicon using conventional microelectronics silicon wafer thicknesses (up to 650um), is close to 100% efficient for...Go to contribution page

Martin Spahn04/09/2012, 10:20X-ray imaging applications - MedicineORALThe applications of x-ray imaging in the medical field are manifold and range from computer tomography (CT), radiography, angiography to mammography. Depending on the application, the x-ray systems support diagnostic and/or interventional procedures and generate 2D (projection) or 3D (volumetric) data sets. The performance requirements for the different application can vary strongly with...Go to contribution page

Toko Hirono (Japan Synchrotron Radiation Research Institute)04/09/2012, 10:50X-ray imaging applications - Material ScienceORALThis study describes a CdTe pixel detector development for the next generation high energy X-ray diffraction experiments at synchrotron radiation facilities. In such applications, a high stopping-power semiconductor material for the sensor and an X-ray photon counting capability for the ASIC are required. A Custom-designed ASIC (SP8-02) has been developed with TSMC 0.25 micron CMOS process,...Go to contribution page

Dr Roberto Dinapoli (Paul Scherrer Institut)04/09/2012, 11:10Pixel technologies - Monolithic detectorsORALEIGER is the next generation single photon counting x-ray detector developed at Paul Scherrer Institut for synchrotron based applications. It is a hybrid silicon pixel detector that features a 75x75 um2 pixel size, a high maximum frame rate capability of ~22 kHz (independent on the detector size), double buffered storage for continuous readout and a negligible dead time between frames of ~3-4...Go to contribution page

Shoji Kawahito (Shizuoka University)04/09/2012, 11:30Pixel technologies - Monolithic detectorsORALThis paper reviews the device and circuit technologies for low-noise CMOS image sensors(CISs) and discusses their future prospect. The first innovation in the low-noise CISs has been done by the CMOS active pixel sensor (APS) using an amplifier and a pinned photodiode in each pixel. The in-pixel amplifier eliminates a large stray capacitance in the signal detection and increases the...Go to contribution page
