Development of experimental technique for investigation of time reversal invariance violation

The advantages of the using polarized neutrons for investigation of Time Reversal Invariance Violation are briefly discussed. The more appropriate method of neutron polarization and nuclear target polarization are considered. A system for adjustment and control of the neutron spin polarization vector are described. The problem of suppression of fake effects and the attainment of acceptable accuracy of measurements are also discussed. The present status and future plans are cited. (author)
