Seminar (IFAE)

Silicon detectors are at the heart of every particle physics collider experiment such as ATLAS at the LHC (and beyond). They provide precise tracking information for momentum determination and vertex reconstruction (e.g. important for the identification of jets originating from b quarks). At the LHC, silicon detectors have to work under extreme conditions such as high rates and harsh radiation environments. Ongoing and planned upgrades like the Insertable B-Layer (IBL, 2014), the ATLAS Forward Physics (AFP) experiment (2015/16) and the High-Luminosity LHC (2022) even present more stringent requirements. New radiation-hard detector technologies are required, such as 3D detectors or detectors with charge multiplication. Such technologies are developed by CNM and IFAE in Barcelona. This presentation will give an overview on the working principles of these new devices and show experimental results of their performance.
