In our proposal, we aim at studying the dissipative states created by a current pulse exceeding the pair-breaking current of the filament. We will focus on the effect of the environment on the non-equilibrium state. We study the formation of a localized spot under vacuum and in the liquid helium bath. The resistive state appears after certain obstruct time (td). The delay time is probed for different current values, and considered for two surrounding environment (He bath and vacuum). It is analyzed with the theoretical model proposed by the Time Time-Dependent Ginzburg-Landau (TDGL) theory modified by Tinkham. The heat escape time is derived from fitting the experimental data with the TDGL theory.
