Development of an FPGA-based FE-I3 pixel readout system and characterization of novel 3D and planar pixel detectors

USBpix is an FPGA-based test and readout system which was developed for the ATLAS FE-I3 pixel readout chip. The main part of this diploma thesis covers the code maintenance and further development of the USBpix test system. Particular attention will be given to the FPGA code which was redesigned during this work. In another step to become a fully integrated test system, USBpix was adapted to the requirements of the EUDET JRA1 beam telescope. In a second part, the USBpix test system was used for laboratory characterizations of pixel sensors bump bonded to FE-I3 pixel readout chips. All investigated sensor types, planar n-on-n and n-on-p, and 3D n-in-p, are candidates for future upgrades of the ATLAS pixel detector (IBL and HL-LHC). Detailed charge collection e ciency and noise studies were made on unirradiated as well as irradiated detectors.
