WG 14 - TC 90/WG 14

IEC 61788-22-3:2022 is applicable to the measurement of the dark count rate (DCR, RD) of superconductor strip photon detectors (SSPDs). It specifies terms, definitions, symbols and the measurement method of DCR that depends on the bias current (Ib) and operating temperature (T).
NOTE The data of measurement results in Annex A are based on measurements of one institute only. The standard will be updated after the data of a complete round robin test are available.

IEC 61788-22-2:2021 is applicable to high-Tc Josephson junctions. It specifies terms, definitions, symbols and the measurement and estimation method for normal state resistance (Rn) and intrinsic critical current (Ici), based on a combination of selecting a data set from measured U–I curves with a geometric mean criterion and fitting a hyperbolic function to that data set.

IEC 61788-22-1:2017 describes general items concerning the specifications for superconducting sensors and detectors, which are the basis for specifications given in other parts of IEC 61788 for various types of sensors and detectors. The sensors and detectors described are basically made of superconducting materials and depend on superconducting phenomena or related phenomena. The objects to be measured (measurands) include magnetic fields, electromagnetic waves, photons of various energies, electrons, ions, a‑particles, and others.
