Issues addressed and main goals of research:
Realization of the NA62 Project allows to clarify CP-violation problem, to measure precisely very rare charged kaon decay to charged pions and two neutrinos, to carry out a search for supersymmetric particles and their partners with a goal to observe a physics beyond the Standard Model. In addition, characteristics of rare kaon and hyperon decays will be improved. A high resolution straw-detectors of the NA62 magnetic spectrometer working in vacuum will be supported during experimental runs. Software for simulation, data processing and analysis will be developed.
The Na64 experiment is a fixed-target esperiment at the CERN SPS combining the active beam dump and missing energy techniques to search for rare events. The experiment will build and operate a fully germetic detector with the primary goal to search for light dark bozons (Z') from dark sector that are coupled to photons, e.g. dark photons (A'). (A') and other manifestation of Dark Sector. Tracking detectores based on the straw tube technology will be manifactured and supported. The software for data MC simulation and analysis will be prepared.

Expected results in the current year:
      In frame of NA62:
  1. NA62 and NA48/2 data analysis will be carried out.

  2. Software for the simulation of magnetic spectrometer and full set-up will be developed; system for detector calibration and event reconstruction will be upgraded; common software of the experiment will be developed.

  3. Calibration and testing of the NA62 straw detectors will be carried out.
      In frame of NA64:
  1. NA64, analysis of the experimental data obtained during the 2017--2018 runs.

  2. Development and put in operation of new track stations based on 6~mm straw tubes. Accompanying of detectors.

  3. Equipment preparation for the 2021 run in the new experimental zone on the H4 SPS channel, CERN.
