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

Abstract
The NA62 GigaTracker is a low mass time tagging hybrid pixel detector operating in a beam with a particle rate of 750 MHz. It consists of three stations with a sensor size of 6027mm2 containing 18000 pixels, each 300300mm2. The active area is connected to a matrix of 25 pixel ASICs, which time tag the arrival of the particles with a binning of 100 ps. The detector operates in vacuum at -20 to 0C and the material budget per station must be below 0.5% X0. Due to the high radiation environment of 21014 1MeV neutron equivalent cm2/yr1 it is planned to exchange the detector modules regularly. The low material budget, cooling requirements and the request for easy module access has driven the electro-mechanical integration of the GigaTracker, which is presented in this paper.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
