The NA62 GigaTracKer: a low mass high intensity beam 4D tracker with 65 ps time resolution on tracks

Abstract

The GigaTracKer (GTK) is the beam spectrometer of the CERN NA62 experiment. The detector features challenging design specifications, in particular a peak particle flux reaching up to 2.0 MHz/mm${}^2$, a single hit time resolution smaller than 200 ps and, a material budget of 0.5% X${}_0$ per tracking plane. To fulfill these specifications, novel technologies were especially employed in the domain of silicon hybrid time-stamping pixel technology and micro-channel cooling. This article describes the detector design and reports on the achieved performance.
