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).
