WebAt low temperatures, a low C v enhances ΔT for a given ΔE.A type I superconductive detector is designed to operate in the intermediate state where a small ΔT gives rise to a large resistance change ΔR as illustrated in Fig. 14.The ability to amplify ΔR electronically makes the superconductive bolometer an extremely sensitive radiation detector; it is particularly … Metal bolometers usually work without cooling. They are produced from thin foils or metal films. Today, most bolometers use semiconductor or superconductor absorptive elements rather than metals. These devices can be operated at cryogenic temperatures, enabling significantly greater sensitivity. See more A bolometer is a device for measuring radiant heat by means of a material having a temperature-dependent electrical resistance. It was invented in 1878 by the American astronomer Samuel Pierpont Langley See more The first bolometers made by Langley consisted of two steel, platinum, or palladium foil strips covered with lampblack. … See more The term bolometer is also used in particle physics to designate an unconventional particle detector. They use the same principle described … See more The hot electron bolometer (HEB) operates at cryogenic temperatures, typically within a few degrees of absolute zero. … See more A bolometer consists of an absorptive element, such as a thin layer of metal, connected to a thermal reservoir (a body of constant … See more While bolometers can be used to measure radiation of any frequency, for most wavelength ranges there are other methods of detection that are more sensitive.
