The secret of doing great physics? Excellent electronics for detector systems!

Febbraio 3, 2016 Non categorizzato 321 Views

In physics experiments, detector systems cover a fundamental role in detecting events associated to the physical phenomena under observation. In such events, particles and photons interact in the detector material and provide an observable signal, e.g. in the form of an electrical charge, which is further processed to extract the information of interest. Electronic amplification and processing allow to improve signal quality for better determination of event parameters such position of interaction, energy, time of arrival. In addition to statistical spread associated to the generated signal itself, the electronics chain adds its own statistical contribution know as electronics noise. Goal of the presentation is to provide an introduction to typical electronics processing chain in detector systems and to intuitive concepts associated to the electronics noise. The approach to maximize the signal-to-noise ratio in electronics systems for detectors is generally introduced and the importance of such approach is highlighted in an example of medical imaging technique as the PET (Positron Emission Tomography).

ABOUT THE SPEAKER

CARLO FIORINI

Carlo Fiorini received the Laurea degree and the Ph.D. from Politecnico di Milano in Electronics Engineering in 1994 and 1998, respectively. In 1999, he joined the Department of Nuclear Engineering of Politecnico di Milano as Assistant Professor, while in 2002 he joined the Department of Electronics and Information Technologies as Associated Professor. In 2010 he has become Full Professor in the same Department. He has carried out part of the research activity at the Max Planck Institut (München, Germany), the University of Siegen (Germany) and the ESRF of Grenoble (France). His primary research interests concern the development of radiation detectors and related applications, and the readout electronics for the detector signals. He has received the “young researcher award” at the Conference “Frontier Detectors for Frontier Physics” in 1997, the “Philip Morris Prize” in 1997 and the “Prof. Luigi Tartufari” Prize from the Accademia Nazionale dei Lincei in 2000. He has participated to several national projects supported by MIUR, INFN, CNR, ASI and international projects funded by European Community and European Space Agency, also as coordinator. He has been committed in research activities by companies like Siemens Medical Solutions (USA), Ion Beam Applications (IBA, Belgium), Osteosys (Korea), PulseTor (USA), Canberra (USA). He is author and co-author of more than 300 papers in international reviews and conference proceedings, and co-author of 6 patents. He is co-founder and President of XGlab, spin-off company of Politecnico di Milano.
