SiPM and its characterization for photon detection experiments

by Dr Hanwen Wang (Institute of High Energy Physics (IHEP))

Wednesday 21 Aug 2024, 10:00 → 12:00 Asia/Shanghai

5#/6th-603 - Meeting Room 603 (Science Building)

Abstract：

This talk will provide a comprehensive overview of Silicon Photomultipliers (SiPMs), covering their fundamental principles, testing methods, and performance characteristics. SiPMs are increasingly important in enhancing the sensitivity and resolution of various photon detection experiments. I will delve into the general concepts of SiPM technology, followed by detailed discussions on our testing protocols to evaluate SiPM key parameters and quality.

To enrich the discussion, I will share insights and experiences from the Taishan Antineutrino Observatory (TAO) and the next Enriched Xenon Observatory (nEXO) projects, highlighting the practical challenges and innovative solutions we developed for SiPM testing. This talk also aims to provide a broad understanding of the current state of SiPM technology and its future prospects in photon detection experiments.

 

Biography: 

Hanwen Wang earned his PhD through a joint program between Université libre de Bruxelles and Beihang University. He subsequently joined the Institute of High Energy Physics (IHEP) as a postdoctoral researcher, where he focused on detector hardware testing for the TAO and nEXO experiments (neutrino physics and 0vbb search). His work primarily involves testing SiPMs and developing low-radioactivity technology. Additionally, he is engaged in optimizing energy resolution and conducting reconstruction studies for general photodetectors.
