First FORTE colloquium

Low-Gain Avalanche Detectors: path towards precise track timing

‍

Abstract:

The upcoming High-Luminosity LHC era necessitates a shift to 4D tracking in High Energy Physics experiments to reduce occupancy from pile-up. This transition requires detectors with excellent spatial resolution, time-tagging capabilities, and higher radiation tolerance. Low-Gain Avalanche Detectors (LGADs) have emerged as a promising technology to meet these challenges.

This seminar explores LGAD developments for precise track timing, covering detection principles and recent design improvements. We introduce the potential of silicon carbide (4H-SiC) in LGADs, a wide-bandgap material that could offer enhanced radiation resistance for inner tracking layers.

Results from lab tests and beam experiments demonstrate the capabilities of these advanced detectors, showcasing good gain uniformity, timing resolution, and energy sensitivity. These findings underscore LGAD technology's potential for next-generation particle detectors in future HEP experiments.
