When a superconductor is disturbed by a high energy deposition, an asymmetry in the distributions of electron-like and hole-like excitations results. This manifests itself as a voltage output, which can be measured in different ways. Here we study the behavior of this quantity using the kinetic equations to model the energy cascade. Special attention is paid to the similarity and differences between the behaviors of normal metals and superconductors. The particular case of tantalum is considered in the modeling.
