### Description

The NA62 experiment is a fixed-target experiment at CERN SPS. The main goal of the experiment is to measure branching ratio of ultra-rare kaon decay $K^+ \to \pi^+ \nu \bar\nu$. The NA62 detector allows also to study other rare kaon decays and processes such as search of very weakly coupled particles of MeV-GeV mass-scale. The new veto hodoscope has been proposed and designed to veto events with halo particles entering the decay volume. The ANTI0 detector is under assembling at CERN now. The detector design, performance simulation and measurements with cosmic rays and test beams for the individual counters are presented. The commissioning and the first run of data-taking scheduled after LS2 (April 2021).
