(Received 22 June 2005; published 12 January 2006)
Time resolved transport measurements on a driven vortex lattice in an undoped 2H-NbSe2 crystal show
that the response to a current pulse is governed by healing of defects as the lattice evolves from a
stationary to a moving steady state and that the response time reflects the degree of order in the initial
vortex state. We find that stationary field cooled vortex lattices become more ordered with decreasing
temperature and identify a temperature below which a qualitative change in the response signals the
disappearance of topological defects.
