The NA62 experiment at CERN SPS aims to collect O(100)K+ → π+νν events in two years of data taking with a S/B ratio of about 10:1. The Branching Ratio (BR) for this decay is ∼ 10 −11 and can be predicted with minimal theoretical uncertainties, making it a sensitive probe for New Physics. The guiding principles for the construction of the NA62 detectors are an accurate particle ID, precise timing and excellent veto efficiency. In particular, the veto inefficiency for photons from K+ → π+π0 decays should be smaller than 10−8. The photon veto system of NA62 consists of three detectors covering different angular regions: Large Angle Veto (LAV), Liquid Krypton calorimeter (LKr) and Small Angle Veto (SAV). The status of the project and present preliminary results from the recent tests will be reviewed.
