CSPAD upgrades at LCLS

The Cornell-SLAC Pixel Array Detector (CSPAD) is the workhorse for LCLS hard x-rays experiments. After deploying three 2.3Mpixel and many 140kpixel cameras, SLAC detector group has focused in improving the detector performances and optimizing its use in experiments. This was achieved first by improving thermo-mechanical assembly, PCB level electronics and firmware. The next step consisted in upgrading the ASIC. Continuous improvements in GUI and DAQ completed the evolution of the CSPAD systems, up to the current version V1.6, and made these cameras easy to use and optimize for a given experiment. More than 85% of the hard x-ray experiments scheduled in run 7 used one or multiple CSPAD cameras.
