Abstract: We study the proximity Josephson sensor in both bolometric and calorimetric operation and optimize it for different temperature ranges between 25 mK and a few kelvin. We investigate how the radiation power is absorbed in the sensor and find that the irradiated system is typically in a weak nonequilibrium state. We show in detail how the proximity of the superconductors affects the device response: for example, via changes in electron-phonon coupling and out-of-equilibrium noise. In addition, we estimate the applicability of graphene as the absorber material.
