Abstract: The NA62 experiment at CERN is aimed at measuring the ultra-rare decay K(+)→ π(+)ν bar nu with 10% accuracy. Since the branching fraction of this decay is O(10(−)(10)), the detector must be able to suppress background events with branching ratios up to 10 orders of magnitude higher than the signal. In order to achieve this goal a set of modern detector systems has been designed and built. Among them is a low mass (~ 1.8% X(0)) spectrometer to detect charged kaon decay products. The spectrometer contains 7168 straw tubes operating in vacuum. The detector was successfully installed and commissioned in 2014–2015. The goal of this report is to give a general overview of the system. The track time resolution obtained from reconstructed data is also described.
