摘要：The Gigatracker is composed of three hybrid pixel detectors in the rare kaon decay experiment, NA62, at CERN, to be installed by the end of 2012. Each station consists of pixel detectors with 18000 300 mm x 300 mm pixels. In order to suppress background events the Gigatracker measures the arrival time of particles with a time binning of 100 ps. Particle hits are then correlated with the signals of a ring imaging cherenkov detector in the experimental setup . The system is operating in vacuum at a temperature of 5C or below. Expected radiation levels are 105 Gy and 2 x 1014 1 MeV neutron equivalent per cm2 over 100 days of operation. This paper describes the detector system, two alternative read out demonstrator ASICs and two cooling options which are considered for final implementation.
