The Gigatracker is a hybrid silicon pixel detector developed for NA62, the experiment aimed at studying ultra-rare kaon decays at the CERN SPS. Three Gigatracker stations will provide precise momentum and angular measurements on the high intensity NA62 hadron beam (0.8-1.0 GHz in total) with a time-tagging resolution of 150 ps per single track. Multiple scattering and hadronic interactions of beam particles have to be minimized, hence the total material budget has been fixed to 0.5% X0 per station, including supports and cooling. The seminar will describe the physics requirements on the Gigatracker performance and the technology choice, discuss the global architecture of the front-end ASIC and the proposed low-mass cooling system. Particular emphasis is placed on recent experimental results obtained from laboratory and beam tests of prototype bump-bonded assemblies.
