This paper describes a 960×960 Frame Store Fast Charge-Coupled Device (CCD) x-ray detector being used for x-ray photon correlation spectroscopy (XPCS) at the Advanced Photon Source (APS) on the 8-ID-I beam line. The detector is typically operated in either the 960 × 960 pixel mode at 100 frames per second (fps) or in the 960×90 pixel mode at 1000 fps. The vacuum subsystems consist of a top board with...
We describe a software library, called MPIFCCD, based on the Message Passing Interface (MPI) for real-time parallel computing on data continuously streamed from the Frame Store Fast Charge-Coupled Device (FSFCCD) Detector located at the Advanced Photon Source (APS) at Argonne National Laboratory. The FSFCCD is used to collect data for X-ray Photon Correlation Spectroscopy (XPCS) experiments at Sector...
Currently, computers can be composed of different Processing Units (PUs) - general-purpose and also programmable and specialist-purpose. One of the goals for such heterogeneity is to improve applications' performance. Particularly, scientific applications can highly benefit from this kind of platform. They produce large amounts of data within several types of algorithms, and distinct PUs are an alternative...
This paper describes the performance of a scalable readout system for high-speed CCD sensors based on the Advanced Telecommunication Computing Architecture specification. The paper reports the readout system performance tested with a 1MPixel Frame Store CCD sensor for soft X-ray applications at synchrotron light sources. This camera is capable of producing image data at over 400 MB/s which must be...
This paper describes the performance of a 1MPixel Frame Store CCD sensor for soft X-ray applications at synchrotron light sources. This camera can be operated in frame store mode with a 1Mpixel imaging area running at 200fps, or in full frame mode with a 2Mpixels imaging area running at 100fps. The CCD has 192 outputs that are serviced by custom-designed integrated circuits that perform correlated...
This work presents the development of a high speed, direct detection, 1k Frame Store CCD camera for synchrotron radiation. We review the research and development of this detector from small scale prototypes to a megapixel sensor, highlighting design challenges and solutions, and reporting on the achieved imaging performance. Further, we report on performance improvements obtained by implementing a...
