The GigaTracKer is a hybrid silicon pixel detector designed for the fixed-target experiment NA62 at the CERN SPS aiming to measure the branching ratio of the very rare kaon decay 𝐾 + → 𝜋 + 𝜈 ¯ 𝜈 with 10% precision. The detector has to provide measurements of momentum, direction and time of beam particles arriving at a rate of 750 MHz. The tracking system consists of four stations installed in vacuum ( ∼ 10 − 6 mbar), 60 . 8 × 27 mm 2 each, with a total material budget of less than 2%X 0 . Each station is cooled with a microchannel cooling plate used for the first time in a high energy physics experiment. The beam particles are tracked in 4 dimensions by means of time-stamping pixels (300 × 300 𝜇 m 2 ) with the single hit time resolution reaching 115 ps. This performance has to be maintained despite the beam irradiation amounting to a yearly fluence of 4 . 5 × 10 14 1MeV n eq / cm 2 / 200 days. The detector has been fully operational since 2016. We describe the GigaTracKer design and performance in the 2016-2022 years of NA62 data taking.
