Superconducting transition-edge bolometer in a resistive and in an inductive mode

Abstract

We analyze the energy resolution of a superconducting transition-edge bolometer (STEB) biased with an ac current. We will show that the ac readout method enables us to utilize STEB either monitoring the change in dissipation due to the change in temperature or the change in inductance owing to the increased in number of quasiparticles.
