1. INTRODUCTION
The response of vortices to applied currents or fields has been a topic of intense
study for almost half a century. Surprisingly, in spite of enormous progress in our
understanding of vortex physics, many of the outstanding questions identified by
Anderson and Kim in 1964, are still unsolved[1]. Their statement " we have made no
progress in studying the transient solutions ... when one quickly applies an external
field or currents to a superconductor" is still valid today. Most experimental studies
on the dynamics of vortices have focused on the evolution of the magnetization to an
applied field in the limit of long time scales[2-4]. The much faster initial transients
occurring in magnetization experiments have received less attention. Similarly few
experiments have focused on the response of a superconductor to a suddenly applied
current.
