Detection Principles, Signals, and Signal Processing in Particle Detectors
- This tutorial will begin with an overview of the physical processes and detection principles employed in modern particle detectors.
- It will then discuss the characteristic signals produced by a variety of detector types and the mechanisms underlying their generation.
- Furthermore, the tutorial will cover detector noise characteristics and the signal-processing techniques used to extract and optimise the relevant information.
- Finally, the requirements for detector development at future accelerators, such as the FCC, and their impact on sensor and electronics specifications will be discussed.
- The seminar will conclude with a 30-minute "Ask Me Anything on Particle Detectors" session, during which participants are invited to ask general questions related to particle detectors and their applications. To facilitate a productive discussion, participants are encouraged to submit their questions to the speaker by e-mail (werner.riegler@cern.ch) a few days in advance.

Given by Dr. Werner Rieger
Werner Riegler is an Austrian experimental particle physicist at CERN who has played a leading role in the development of particle detectors for the Large Hadron Collider (LHC) for more than three decades. He is particularly known for his contributions to the ATLAS, LHCb, and ALICE experiments, as well as for his work on detector physics and future collider concepts.
Contributions to LHC Experiments
He is the technical coordinator of the ALICE Collaboration, overseeing detector installation and integration and has been responsible for major detector upgrades and operational coordination.
Detector Physics Research
Beyond large detector projects, Riegler is widely recognised for his theoretical and practical contributions to particle detector instrumentation. His work spans:
- Detector simulation and signal formation
- Front-end electronics for particle detectors
- Fundamental limits of measurement precision
- Gas detectors and resistive detector technologies
- Silicon detectors
He is also the author of widely used lecture notes and courses on particle detector instrumentation, including CERN schools and advanced training programs.
Future Circular Collider (FCC)
Since 2015, Riegler is involved in detector and experiment studies for the proposed Future Circular Collider, helping define the detector concepts and technology requirements for a next-generation hadron collider beyond the LHC.
Summary
Werner Riegler is regarded as one of CERN’s leading experts in particle detector instrumentation. His career spans the development of major LHC experiments, leadership of the ALICE detector, and research into the fundamental principles of particle detection and measurement, while also shaping detector concepts for future accelerators such as the FCC.
