With the successful operation of three 2.3 megapixel, 120Hz readout rate, hybrid pixel array detectors at the Linac Coherent Light Source (LCLS), the SLAC National Accelerator Laboratory detector group is now exploring additional applications based on the same detector platform. These megapixel cameras are based on the Cornell-SLAC hybrid Pixel Array Detector (CSPAD). The CSPAD platform is developed around the CSPAD ASIC, a 36 kilopixel device, each pixel at 110x110 mu m^2. Important characteristics of the CSPAD (room temperature operation, 14bit on chip digitization with a purely digital data interface, and scaling modularity) make it an effective choice for designing detector variants that are optimized for a range of experiments and applications. One of the first spin-off detectors based on this proven CSPAD platform is the CSPAD-140k: a 140 kilopixel detector, with an active area of approximately 4x4cm2 24 and four ASICs, bundled in a small, inexpensive and easy-to-deploy package. Due to its versatility it has already been used successfully in several experiments at the CXI, XPP and XCS instruments at LCLS. The work also describes problems faced by scaling from a prototype system to a full size x-ray camera and presents the current status on the improvements achieved. Show Partial Abstract
