Abstract :
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 2M pixels imaging area running at 100fps. The CCD has 192 outputs that are serviced by custom-designed integrated circuits that perform correlated double-sampling signal processing and digitization. The digitized data is acquired by a custom made image acquisition and camera controller board based on the Advanced Telecommunication Computing Architecture system. Results obtained during a test run at the Advanced Light Source are presented demonstrating the X-ray camera performance.
