X-ray imaging applications - Material Science
ORAL
The 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...

X-ray imaging applications - Material Science
ORAL
We 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...

X-ray imaging applications - Material Science
ORAL
At 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...

X-ray imaging applications - Medicine
ORAL
The 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...

X-ray imaging applications - Material Science
ORAL
This 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,...

Pixel technologies - Monolithic detectors
ORAL
EIGER 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...

Pixel technologies - Monolithic detectors
ORAL
This 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...
