CMS Tracker


The silicon tracker (link opens in a new window) is at the heart of the CMS detector. It makes precise measurements of the paths of charged particles as they pass through the CMS magnetic field, allowing the main event vertex, and secondary vertices from decays of heavy quarks, to be reconstructed very precisely. The PPD group worked closely with RAL electronics engineers to design readout electronics for the tracker detector, has been closely involved in beam tests of the detector, and continues to make a substantial contribution to the development of reconstruction and simulation software.
