The Gigatracker is the NA62 beam tracker. It is made of three $63.1 mm \times 29.3 mm$ stations of $300 \mu m \times 300 \mu m $hybrid silicon pixel detectors installed in vacuum ($\sim10^{-6} mbar$).
The beam particles, flowing at 750 MHz, are traced in 4-dimensions by means of time-stamping pixels with a design resolution of $200 ps$. This performance has to be maintained despite the beam irradiation amounting to a yearly fluence of $2 \times 10^{14}~1\,\rm{MeV~eq.~n /cm^{2}}$.
The detector material minimization is paramount, as the detector faces the full beam. The station material budget is reduced to $0.5\% X_0$ by using (HEP world first) microchannels cooling.
We will describe the detector design and performances during the NA62 runs.
