  We demonstrate that study of large t vector meson photoproduction with
rapidity gaps in ultraperipheral proton-ion and ion-ion collisions at LHC would
allow to investigate the energy dependence of cross section of elastic
scattering of a small dipole off the parton over a wide range of energies $10^3
< s_{dipole - parton} < 10^6 GeV^2$ where this cross section is expected to
change by a factor $\ge 20$. The accessible energy range exceeds the one
reached at HERA by a factor of 10 both in $\gamma p$ and in $\gamma A$
scattering. In addition, study of A-dependence of this process will allow to
determine the t range where interaction of small dipoles gives the dominant
contribution and to investigate effects of absorption for the propagation of
ultrarelativistic small $q\bar q$ dipoles through the nuclear media and probe
in a novel way onset of the black disk regime.
