Chapter 7Summary and OutlookA small and lightweight test and readout system was developed for the ATLASFE-I3 pixel readout chip. In addition, measurements were performed on a newgeneration of pixel sensors, which are possible candidates for the ATLAS IBLupgrade. High-statistics laboratory characterizations with — radiation and noisestudies of the pixel sensors delivered valuable information about charge collectione ciency and noise performance.USBpix has proved its functionality in laboratory characterizations as wellas at beam test at CERN. The integration of USBpix into the JRA1 EUDETbeam telescope was a big step closer to a fully integrated test system. Especiallydata taking at high trigger rates has proved to work reliably so that USBpixwill become the successor of TurboDAQ.Beside the changes that have made to the USBpix test system during thisthesis, there is still room left for further improvements. As mentioned earlier, theUSB driver needs to be reworked to work with modern Linux-based systems.The seamless integration of USBpix into the EUDET framework is a majormilestone in the near future.77
