Experimental study of superconducting transition in a molybdenum–copper thin film structure showing the proximity phenomenon and the estimation of the sensitivity of TES bolometers on the basis of such a structure

Mo/Cu bi-layers with different layer thickness values showing superconducting transitions in the temperature range 0.08–1.0 K have been experimentally studied. The temperature of the superconducting transition can be adjusted to the stable temperatures of refrigerators used at the space radio telescopes using the proximity phenomenon by varying the thickness of Mo and Cu layers. The estimation of the noise equivalent power of TES bolometers on the basis of such structures using measured dependences of Mo/Cu structure resistances on temperature and electron energy balance equation is fulfilled.
