 Fully operational Gigatracker at NA62An important milestone has been accomplished by NA62 collaboration with the completion of the three Gigatracker stations. As it can be seen in the picture, high intensity SPS beam can be fully tracked by NA62 with a time resolution of <200 ps. This installation is essential to fully exploit the capabilities of NA62 and opens the door to a 10% measurement of the very rare decay $K^+\to\pi^+\nu\bar{\nu}$<\latex> By Eduardo Cortina Gil on October 2, 2016
The main goal of the NA62 experiment is the detection or ~100 events of the very rare decay $K^+\to\pi^+\nu\bar{\nu}$<\latex>, (BR ~ 10-11) in two years of data taking with a signal over noise ratio greater than 10.
The Gigatracker (GTK) is a pixel detector with excellent spatial resolution (~80 $\mu$ m) and temporal resolution ($\sigma_t$<170 ps). It consists in three station with 18.000 pixels each placed around an achromat spectrometer and it allows the measurement of individual tracks in a 750 MHz high intensité beam from SPS.
