Abstract
The behavior of a superconducting tunnel junction detector (STJ) in th e regime of low excitation is described, and the characteristic times of the dynamical response are discussed. The effect of a proximity lay er in the STJ is analyzed in terms of the McMillan model. A set of phe nomenological equations for the proximized STJ driven out of equilibri um is obtained, showing the importance of the role of the proximity ef fect in the dynamics of the device.
