506 (Nielsen)

Precision timing at the tens of picoseconds level is a fundamental ingredient of all planned future high-energy physics experiments as well as a plethora of ongoing upgrades to existing detector systems. Superfast timing detectors enable enhanced vertex reconstruction, pileup mitigation, and new approaches to fundamental measurements.

In this seminar, I will provide a pedagogical introduction to the principles and techniques required for achieving ultrafast timing resolution, including the role of silicon sensors, front-end electronics, and signal processing methods. I will then present recent highlights in fast silicon sensor technologies such as Low-Gain Avalanche Detectors (LGADs) and advanced CMOS-based timing detectors, discussing their impact on current and future experiments. Finally, I will showcase recent experimental results that push the boundaries of time resolution in particle detection. This talk aims to bridge the gap between fundamental concepts and state-of-the-art advancements, providing insights into the exciting future of precision timing in particle physics.
