Description

The Gigatracker is an hybrid silicon pixel detector built for the NA62 experiment aiming 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 beam with a flux reaching 1.3 MHz/mm2 and provide single-hit timing with 200 ps RMS resolution for a total material budget of less than 0.5% X0 per station. The tracker comprises three 63.1 mm × 29.3 mm stations installed in 106mbar vacuum and cooled with liquid C6F14 circulating through microchannels etched inside 130 um thick silicon plates. Each station is composed of a 200 um thick silicon sensor readout by 2×5 custom 100 um thick ASIC, called TDCPix. Each chip contains 40×45 asynchronous pixels, each 300 um × 300 um, and is instrumented with 100 ps bin time-to-digital converters. In order to cope with the high rate, the TDCPix is self-triggered and data are sent out through four 3.2 Gb/s serialisers. We will describe the detector and the results from the 2014 NA62 run.
