“…In addition, the amount of material in the beam acceptance has to be as small as possible. To fulfil these requirements a micro-channel cooling device was developed [14]. The implementation of such a device is the world's first for high energy physics.…”

A: 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 fulfil 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.

“…The GTK stations dissipate about 35 W each and are installed in vacuum (∼10 −6 mbar) , therefore an efficient cooling system, and with very low material budget (about 0.15% X 0 in the active beam area) is necessary for stable detector operation. A micro-channel cooling solution has been adopted by the NA62 Collaboration for the first time in a high energy physics experiment [9,10]. In addition, the detector is exposed to high and non-uniform radiation levels: the expected fluence is about 2×10 14 1 MeV n eq /cm 2 during 100 days of operation in the sensor center, and a regular exchange of detectors is performed to mitigate performance degradation due to radiation damage.…”

The Gigatracker is a hybrid silicon pixel detector developed for the NA62 experiment at CERN, which aims at measuring the branching fraction of the ultra-rare kaon decay K + → π + νν at the CERN SPS. The detector has to track particles in a 75 GeV/c hadron beam with a flux reaching 1.3 MHz/mm 2 and provide single-hit timing with better than 200 ps r.m.s. resolution for a total material budget of less than 0.5% X 0 per station. The tracker comprises three 61×27 mm 2 stations installed in vacuum (about 10 −6 mbar) and cooled with liquid C 6 F 14 circulating through microchannels etched inside few hundred of microns thick silicon plates. Each station is composed of a 200 µm thick planar silicon sensor bump-bonded to 2×5 custom 100 µm thick ASIC, called TDCpix. Each chip contains 40×45 asynchronous pixels, each 300×300 µm 2 and is instrumented with 720 time-to-digital converter channels with 100 ps bin. In order to cope with the high rate, the TDCpix is equipped with four 3.2 Gb/s serializers sending out the data. Detector description, operational experience and results from the NA62 experimental runs will be presented.
