Research Interests

Elementary Particle Physics is an exciting and challenging field. Sadrozinski works on the experimental side, and the excitement comes from investigating and ultimately understanding the interaction of the fundamental building blocks of nature. The research is carried out both on particle accelerators, where he investigates the breaking of symmetry principles like CP violation in Babar and the Higgs phenomenon at the LHC, and in Space, for which he is preparing the GLAST mission to search for the most powerful accelerators in nature.

The challenge of the experimental work lies in keeping the detector technology abreast of the requirements of the experiments. My research is centered on the application of silicon strip detectors in Elementary Particle Physics and Astrophysics. Although this technology has matured in the more than 10 years of use, its large-scale use required the optimization for the specific experimental conditions. For example, in the ATLAS experiment at the proton-proton collider LHC (CERN), the problem of radiation damage has to be solved, while in the space mission GLAST, reliability and large size are the key questions.

Collaboration Involvement: ATLAS, BaBar, GLAST, ZEUS
