Wednesday 28 January 2015 Speaker: Dr Gianluigi Casse (University of Liverpool) Title: "Status and trends of silicon detectors for collider physics" Abstract: Silicon detectors are the devices of choice for vertex and tracker systems in high energy and (increasingly) nuclear physics experiments. This is due to their speed, low mass, relatively low cost and their surprising radiation tolerance. These characteristics have evolved over several order of magnitude since the introduction of segmented silicon sensors for tracking in the 1980’ in CERN experiments. Their evolution is not slowing down. A review of the state-of-the-art and of current trends is given.
