We present measurements on one-dimensional Josephson junction arrays formed by a chain of SQUID loops in the regime where EJ / Ec≃ 1. We observe a blockaded zero current branch for small bias voltages. Above a certain voltage Vsw the I-V characteristics changes discontinuously to a dissipative branch characterized by a flux dependent conductance. Three of four samples show a pronounced hysteresis for a forward and backward voltage sweep. We observe a periodic field dependence of the conductance above Vsw which can be described with P(E) theory for cooper-pairs and therefore gives evidence of viscous dynamics of Cooper pair transport through the array.
