Characterization of 3D Silicon Assemblies for ATLAS Pixel Upgrade
The ATLAS pixel detector will be upgraded with a new Insertable B-layer (IBL). The IBL will be inserted between the existing pixel detector and the reduced diameter vacuum pipe of the Large Hadron Collider. The extreme operating conditions at this location have required the development of new radiation hard pixel sensor technologies and a new front end chip.3D-silicon sensors will populate 25% of the IBL sensing area. They are a newgeneration of micro-machined sensors with electrodes etched inside the silicon bulk rather than on the wafer surface. 3D-silicon sensors were studied by performing simulations, laboratory measurements and beam tests on irradiated and not irradiated samples. This thesis describes the development of a fast algorithm of the signal response in 3D-silicon sensors using Geant4 simulations. The simulation of the signal response is compared to actual data from test-beam and radioactive source measurements. The setup for each of these measurements is also simulated in Geant4 using experience gained after working with the real setup.

Radiation Sensors with 3D Electrodes
Written by the leading names in this field, this book introduces the technical properties, design and fabrication details, measurement results, and applications of three-dimensional silicon radiation sensors. Such devices are currently used in the ATLAS experiment at the European Centre for Particle Physics (CERN) for particle tracking in high energy physics. These sensors are the radiation hardest devices ever fabricated and have applications in ground-breaking research in neutron detection, medical dosimetry and space technologies and more. Chapters explore the essential features of silicon particle detectors, interactions of radiation with matter, radiation damage effects, and micro-fabrication, in addition to a providing historical overview of the field. This book will be a key reference for students and researchers working with sensor technologies. Features: The first book dedicated to this unique and growing subject area, which is also widely applicable in high-energy physics, medical physics, space science and beyond Authored by Sherwood Parker, the inventor of the concept of 3D detectors; Cinzia Da Vià, who has brought 3DSi technology to application; and Gian-Franco Dalla Betta, a leading figure in the design and fabrication technology of these devices Explains to non-experts the essential features of silicon particle detectors, interactions of radiation with matter, radiation damage effects, and micro-fabrication
