Introduction

Superconducting characteristics such as superconducting energy gap, narrow superconducting state-normal state transition, nonlinear current-voltage curve, superconducting coherent state, magnetic flux quantumization, etc:,

Will be affected by electromagnetic fields, photons, ions, etc: Various superconducting sensors and detectors have been developed using these different superconducting properties: they

In terms of energy resolution, time response, and noise characteristics, it has extremely high performance that is difficult to achieve with other non-superconducting devices:

The term "sensor" usually refers to a device or device used to measure physical quantities such as static or slowly varying electromagnetic fields, currents, and temperature: While "probing

"Device" usually refers to a device that observes and records single quantum states, such as photons from infrared to gamma rays, single particles, etc: However,

The boundary between "sensor" and "detector" is blurred: Therefore, both words will be used in this document: In addition, the sensor is used to detect

Sensors are also feasible: For example, the superconducting transition edge sensor (TES) is used for X-ray detectors:

The resulting temperature rise can be detected: Therefore, in this standard, the term "superconducting transition edge sensor X-ray detector" is used to indicate the use of TES

A device or device for X-ray detection:

Superconducting sensors and detectors have been used in many fields, including medical diagnosis, communications, mineral exploration, astronomical instruments, and quantum information processing

And analytical instruments, etc: For users, there is currently a lack of unified specifications for related professional terms, legend symbols and test methods, so it is very

It is necessary to establish a unified standardized document:

Superconducting device

General specifications for sensors and detectors

1 Scope

This standard gives general specifications for superconducting sensors and detectors: These are the various types of sensors in other parts of IEC 61788:

And the basis of the specifications of the detector: The sensors and detectors are mainly composed of superconducting materials and rely on superconductivity or related phenomena: Under test

Standards (physical quantities) include magnetic fields, electromagnetic waves, photons of different energy, electrons, particles, alpha particles and others:
