What is it about?

Detectors convert physical quantities to electrical signals so that they expand our vision to nature. Analytical instruments such as scanning electron microscopes, synchrotron radiation facilities, mass spectrometry require detectors to detect X-rays, ions, molecules, and biomacromolecules. This tutorial explain basics of detectors: quantum detectors that produce electric signals directly and thermal detectors that utilized temperature rise because of signal input.

Why is it important?

Normally, semiconductor detectors are used for analytical instruments. When we introduce superconductor detectors, it is possible to overcome the fundamental limits of conventional analytical instruments.


This tutorial explain the history of superconductor detectors as well as scientific description. The readers can follow the works by the pioneers and learn the advances realized by modern researchers. The matured superconductor detectors contribute to a wide range of fields, such as dentistry, molecular biology, energy-saving society, planetary science, and prebiotic organic molecules in space.
