Search for Effects of Polarized Hidden Strangeness in Nucleons
(Project NIS)

Scientific Programme:

• Obtaining new experimental data on total and differential cross sections of and production in pp and np interactions at thresholds.
  
  
• Experimental and theoretical studies of vector meson production mechanisms at threshold in nucleon-nucleon interactions at intermediate energies.
  
  
• Data on OZI-rule violation, its energy dependence and dependence on isospin of the NN system in the initial state at nucleon energies close to the and meson production thresholds.
  
  
• A new large acceptance magnetic spectrometer for experiments at intermediate energies with multitracking capability and particle identification system (PID) based on time-of-flight measurements will be created at the Nuclotron extracted beam.

• Test, upgrade of MWPC of the EXCHARM setup and transportation to LHE, bld.205.
  
  
• Test-bench and test-beam studies of the tracking system in bld.205 (LHE). Installation of the tracking system and its comissioning.
  
  
• Measurement and data analysis of the 3-dimension field map of the analyzing magnet at SPHERE setup.
  
  
• R&D of the trigger and particle-identification subsystems. Test of the prototypes at the test-bench. Purchase of elements and modules for front-end electronics and for detector power supplies for trackers and the PID subsystem.
  
  
• Detailed Monte-Carlo simulation of the experiment. Study of the Nuclortron beam parameters and physical background at SHERE beam-line. Preparation of the project for radiation protection shield of the setup. Production of elements of the radiation protection.
  
  
• R&D of the software for event reconstruction, on-line and off-line analysis.
  
  
• Production of the thin liquid hydrogen target.
