Radiation Hard Timing 3D Detectors for Future Colliders

Abstract

In this thesis, radiation hard detectors are studied in view of the upcoming High-Luminosity LHC upgrade and the Future Circular Collider. The increase in luminosity requires sensors to withstand unprecedented radiation levels. 3D silicon sensors are a promising candidate due to the short inter-electrode distance which yield high radiation hardness and fast signals, required for good timing performance. In this work, 3D sensors are characterized with I-V and C-V curves, studied with infrared laser in a Transient Current Technique (TCT) setup, and with a strontium-90 source setup. Moreover, simulations have been performed for 3D sensors designed for timing applications, comparing a novel hexagonal geometry with the common orthogonal one.
