Development of experimental technique for investigation of Time Reversal Invariance violation

The advantages of the using polarized neutrons for investigation of Time Re versal Invariance (TRI) Violation are breafly discussed. The more appropria te method of neutron polarization and nuclear target polarization are consi dered. A system for adjustment and control of the neutron spin polarization vector are described. The problem of suppresion of fake effects and the at tainment of acceptable accuracy of measurements are also discussed. The pre sent status and future plans are cited.
