Radiation Hard Timing Detectors for Future Colliders

Òscar Ferrer

The thesis explores the challenges posed by the forthcoming upgrade of the LHC and the future particle colliders concerning the silicon sensors utilized in their experiments. These challenges entail the necessity for greater radiation hardness and enhanced time resolution due to the higher amount of collisions per unit of time. Among the most promising candidates are the so-called "3D sensors," featuring columnar electrodes etched towards the silicon wafer.

About the speaker

Born in the region of Anoia, Catlunya, I graduated in Physics in 2018 in the Universitat de Barcelona, and later completed a master's degree in Nanoscience and Nanotechnology in 2019, at the same university. For 4 years, I have been part of the radiation detectors group, and currently, I am in the process of writing my thesis focused on characterizing silicon detectors intended for future colliders, which are capable of withstanding high doses of radiation while achieving good time resolution to resolve closely timed particle tracks.

Design and development of Low Gain Avalanche Diodes (LGAD) at IMB-CNM

Jairo Villegas

The Low Gain Avalanche Diode (LGAD) is a kind of silicon-based particle detector that was pioneeringly conceptualized and fabricated at IMB-CNM. Since its conception and materialization, the LGAD has demonstrated to be an outstanding asset for many applications that require particles to be detected, ranging from high energy physics, synchrotron, medical and space applications. An overview of the historical, current, and prospective landscape of the LGAD performance, potential implementations, design and fabrication is presented in this work.

About the speaker

Born in Malaga, Andalusia, I graduated in Physics in 2017 by the University of Granada. After that, I achieved an interuniversity master's degree in Nuclear Physics (2019) at the Universities of Barcelona, Salamanca, Granada, Autónoma of Madrid, Complutense of Madrid and Seville. In particular, my master thesis was carried out at Centro Nacional de Aceleradores (CNA) in Seville. I have been working at IMB-CNM for the radiation detectors group since 2020. During 2022, I stayed in Scotland for three months, collaborating with the Physics department of the university of Glasgow. The main objective of my thesis work is the design and development of LGAD sensors for particle detection applications.
