Typically, quasiparticles are injected into superconductors at energies comparable to the pairing energy in order to gain insights into quasiparticle dynamics. Tunnelling spectroscopy of a mesoscopic superconductor under high electric field now provides insights into a regime where electrons impinge with 106 times the pairing energy.
