  A possible experimental setup for measuring the effect of parity violation in
the interaction of the polarized proton or deuteron beams with an unpolarized
target is discussed. One possibility is investigation of scattering of the
proton or deuteron polarized beams on a thick internal target in one of the
rings of the NICA collider. In this case, the spin of a circulating particles
is transformed into a mode precessing in the horizontal plane using an RF
flipper. The effect of parity violation will be studied by measuring the
correlation of the interaction cross section of particles and the direction of
their spins. In an alternative approach, the flipper transforms the spins of
particles into a horizontal plane and the beam is extracted into the channel in
a certain phase of the precession. In this more traditional experimental setup,
the total cross section of the passage of particles through a dense target is
measured, depending on the sign of the helicity of the polarization of the
beam.
