Sommario
On June 9th, 2023 at 2.30 pm Dr. Nicolò Cartiglia, Director of research at INFN, Section of Torino, will hold a seminar on "Resistive read-out and built-in amplification: two key innovations in the design of silicon sensors" in DEIB Alpha Room (Building 24).
In the past few years, two design innovations have radically changed the performance of silicon detectors and turned silicon sensors into high-resolution timing detectors, fit to meet the very demanding requirement of future space-time particle trackers. In this presentation,
I will review the performance improvements that these two design innovations, low-gain (LGAD) and resistive read-out (RSD), have brought to silicon sensors. Due to the LGAD mechanism, large signals lead to improved temporal precision, while charge sharing, due to the RSD design, has removed the need for very small pixels to achieve excellent spatial precision. LGAD- and RSD- based silicon sensors are now adopted, or considered, in several future experiments and are the basis for almost every next 4D-trackers. In the final part of the presentation, I will review the needs and the development of the front-end electronics.

Biografia
Dr. Cartiglia is a director of research at INFN and an associate professor at the University of California. His field of research is detector design, construction, and commissioning.
He has been a member of several large collaborations based both in Europe and the US. Throughout his carrier, he has complemented his work on detector innovation with a strong involvement in physics analyses. In the past 10 years, he has focused his efforts on developing innovative silicon detectors, specifically for tracking particles in space and time, the so-called 4D tracking. He has been the PI of important projects, including an ERC advanced grant and an Italian PRIN grant.
