Abstract

The physics aims of future lepton colliders such as CLIC pose challenging demands on the performance of the detector system. In particular, the vertex and tracking detectors have to combine a spatial resolution of a few micrometres and a low material budget with a few nanoseconds time-stamping accuracy. To address these requirements a broad R&D programme on silicon detector technologies is pursued within various collaborative frameworks such as the CERN EP R&D program, AIDAinnova and the CLICdp collaboration. For the vertex detector, fine-pitch hybrid pixel detectors with dedicated 65nm readout ASICs as well as hybridisation techniques using solder bumps or anisotropic conductive films are explored. Fully-integrated monolithic CMOS sensors are under investigation for the large-surface CLIC tracker. This seminar gives an overview of the CLIC vertex and tracking detector R&D, focussing on recent results from test-beam campaigns and simulation-based sensor optimisation studies.
