Simulation software for transition-edge sensor performance prediction

TES calc is a free access online calculator that allows you to predict the behavior of your Transition-Edge Sensors exploiting most of the established theory in this field. The program gives you freedom in the selection of materials, geometries, models and other inputs. This allows you to better fit your device and conditions. The outputs involve all the main characteristics and a great number of graphs in a single simulation. You can find it at Try it now.
