Description
Sensors with fast timing capabilities (on the order of tens of picoseconds) are a critical component of future tracking detectors. Such sensors provide the ability to disentangle high multiplicity events and to conduct time of flight measurements for particle ID. Silicon 3D sensors are capable of delivering this temporal resolution and additionally display an excellent radiation hardness, suitable for the harsh environments expected in future hadron colliders (e.g. FCC-hh). In contrast to regular, planar, detector technologies, they utilize columns etched orthogonal to the sensor substrate as their readout electrodes
In the course of the collaborative project "3D detectors optimized for timing applications", double-sided 3D sensors with two different column layouts, hexagonal and orthogonal, and different column counts were designed and produced by CNM.
In this work, the results of fast timing measurements with a source setup as well as Top-TCT measurements will be presented. Furthermore, first data of proton-irradiated sensors will be shown.
