Abstract

Niobium-based superconducting tunnel junctions are expected to be applicable to high resolution X-ray measurements. Large-size tunnel junctions with a Nb/Al /A10x/Nb structure have been fabricated in order tc study their performance in X-ray detection. The junction detected 5.9 keV X-rays with an energy resolution of 1 keV. Output signal is analyzed by the use of coupled Boltzmann equations. The method based on these equations clarifies the basic behavior of the quasiparticles and phonons, and the average energy for producing a single electron amounts to 3.2Δ.
