Precision timing with silicon sensors — •Annika Vauth — Institut für Experimentalphysik, Universität Hamburg, Luruper Chaussee 149, 22761 Hamburg, Deutschland

Precision timing with silicon is an important tool in many areas of particle physics, either by adding a dedicated timing layer for track timing to a detector, or full “4D-tracking” where precise space and time coordinates are assigned to each hit.

Intense R&D is taking place in the design and optimisation of different types of silicon sensors to achieve excellent timing performance. Two examples for promising technologies are Low Gain Avalanche Diodes, which have been shown to achieve time resolutions of 30 ps or better, as well as 3D sensors, which display excellent radiation hardness. In this contribution, the currently existing technological solutions and ongoing research addressing the remaining challenges are reviewed. Future applications for precision timing will be presented.
