We study Rydberg states of ions which are trapped in a linear Paul trap. In such trap the ions are confined by an electric quadrupole field and a ponderomotive force due to an oscillating quadrupole. Using a two-body approach in order to model the Rydberg ions we derive the Hamiltonian for Rydberg excitations in a linear ion crystal. We discuss the creation of strong state-dependent dipole-dipole interaction among the ions using microwave dressing of Rydberg states. This system offers the possibility to study Rydberg excitation dynamics of a mesoscopic ensemble in a well-structured environment and allows the implementation of strongly interacting spin models.
