We investigate the current response of Andreev states of an NS ring to a time dependent Aharonov Bohm flux superimposed to a dc one. The ring is modeled with a tight binding Hamiltonian including a superconducting region with a BCS coupling between electron and hole states, in contact with a normal region with on site disorder. Both dc and ac currents are determined from the computed eigenstates and energies using a Kubo formula approach.
