The Gigatracker is the NA62 beam tracker. It is made of three 63.1mm×29.3mm stations of 300μm×300μm hybrid silicon pixel detectors installed in vacuum (∼10 −6 mbar). The beam particles, flowing at 750MHz, are traced in 4-dimensions by mean of time-stamping pixels with a design resolution of 200ps. This performance has to be maintained despite the beam irradiation amounting to a yearly fluence of 2×10 14 1MeVn eq ∕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) micro-channels cooling. We will describe the detector design and performances during the NA62 runs.

Abstract

The Gigatracker is the NA62 beam tracker. It is made of three 63.1mm×29.3mm stations of 300μm×300μm hybrid silicon pixel detectors installed in vacuum (∼10 −6 mbar). The beam particles, flowing at 750MHz, are traced in 4-dimensions by mean of time-stamping pixels with a design resolution of 200ps. This performance has to be maintained despite the beam irradiation amounting to a yearly fluence of 2×10 14 1MeVn eq ∕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) micro-channels cooling. We will describe the detector design and performances during the NA62 runs.
