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.
A large RICH detector is used in NA62 to suppress the muon contamination in the charged pion sample by a factor of 100 in the momentum range between 15 and 35 GeV/c. Cherenkov light is collected by 1952 photomultipliers placed at the upstream end. In
When testing and calibrating particle detectors in a test beam, accurate tracking information independent of the detector being tested is extremely useful during the offline analysis of the data. A general-purpose Silicon Beam Tracker (SBT) was const
The international PEN collaboration aims to obtain the branching ratio for the pion electronic decay $pi^+ to e^+ u_e(gamma)$, aka $pi_{e2}$, to a relative precision of $5times 10^{-4}$ or better. The PEN apparatus comprises a number of detection sys
Timing-pick up detectors with excellent timing resolutions are essential in many modern nuclear physics experiments. Aiming to develop a Time-Of-Flight system with precision down to about 10 ps, we have made a systematic study of the timing character
A semiconductor tracker for muon scattering tomography is presented. The tracker contains silicon strip sensors with an $80,mu$m pitch, precision mechanics and integrated cooling. The electronic readout of the sensors is performed by a scalable, inex
