The electro-mechanical integration of the NA62 GigaTracker time tagging pixel detector

The NA62 GigaTracker is a low mass time tagging hybrid pixel detector operating in a\nbeam with a particle rate of 750 MHz. It consists of three stations with a sensor size of 6027mm2\ncontaining 18000 pixels, each 300300mm2. The active area is connected to a matrix of 25\npixel ASICs, which time tag the arrival of the particles with a binning of 100 ps. The detector\noperates in vacuum at -20 to 0C and the material budget per station must be below 0.5% X0. Due\nto the high radiation environment of 21014 1MeV neutron equivalent cm2/yr1 it is planned to\nexchange the detector modules regularly. The low material budget, cooling requirements and the\nrequest for easy module access has driven the electro-mechanical integration of the GigaTracker,\nwhich is presented in this paper.
