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:
