Design and performance of the ePix camera system

A second generation camera system has been developed and built at SLAC for use in experiments at the Linac Coherent Light Source (LCLS). The system is developed around the ePix family of hybrid pixel detectors, with a focus on modularity in mechanical, electrical, and data acquisition interfaces, allowing for a versatile system that can be quickly reconfigured. The first camera is a compact, 155 mm × 52 mm × 52 mm box, with an active area of up to 35 mm × 38 mm, recording full frames of over 540 kpixel at rates in excess of 120 Hz. The camera allows fast debugging and development, providing a test bench to demonstrate features that may be required at future high repetition rate facilities.
