transition edge sensor

(TES)
(sensor using superconductor's strong resistance sensitivity)

A transition edge sensor (TES) is an instrument that uses a superconductor's extreme temperature sensitivity (at the point of change from zero resistance to "normal" resistance) to sense electromagnetic radiation (EMR). A TES bolometer (i.e., transition edge sensor bolometer) is a bolometer which operates by using the heat induced by the EMR being measured to trigger such a resistance change.

TES bolometers have been used with the South Pole Telescope (SPT) and the Atacama Submillimeter Telescope Experiment (ASTE).
