Newer versions of these devices utilize superconducting materials operated at or near their critical temperature which are known as Transition Edge Sensors.
Newer versions of these devices utilize superconducting materials operated at or near their critical temperature which are known as Transition Edge Sensors. The first one, which operated as two platinum branches of a Wheatstone bridge, was read out by a galvanometer. A technique called "jiggle-mapping" was used to create images on SCUBA, a detector which used these instruments. A principal difference between the current SPT-pol and the upgraded SPT-3G is the tenfold increase in the number of these devices. The surface of these devices, which often appears in a (*) spider web shape, is a thermal absorber, that is then connected to a heat reservoir by a thermally resistant link. For 10 points, name these detectors fundamental to radio astronomy, whose name suggests that they detect all wavelengths of light, like a certain magnitude scale.
