In this new study, researchers at our laboratory have investigated the dynamics of electrons in a superconducting niobium nanowire. The injection of a very small number of electrons is enough to drastically reduce the critical current flowing in a superconductor. This is due to the accumulation of energetic electrons from Cooper pairs broken by this very small injection current.
