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

• 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 a particle identification system (PID) based on time-of-flight measurements will be constructed at the Nuclotron extracted beam.

• Mounting of the tracking system (MWPC, electric and gas supply, readout electronics) at the place of the experiment in bld. 205 (LHE). Comission and start of exploitation. Calibrating measurements at beam.
  
  
• Study of prototypes of the trigger and particle-identification subsystems. Purchase of elements and modules of the front-end electronics and power supplies for trackers and the PID subsystem. Installation of the first hodoscope station.
  
  
• Detailed Monte-Carlo simulation of the experiment. Study of the physical background and trigger system with the extracted proton beam.
  
  
• Preparation of the project for radiation protection shield of the setup. Production of its elements.
  
  
• Creation of the software for event reconstruction, on-line and off-line analysis.
  
  
• Production of the thin liquid hydrogen target.
