2. Compact Muon Solenoid - Wikipedia

   en.wikipedia.org/wiki/Compact_Muon_Solenoid

   This means it produces light in proportion to the particle's energy. These high-density crystals produce light in fast, short, well-defined photon bursts that allow for a precise, fast and fairly compact detector. It has a radiation length of χ 0 = 0.89 cm, and has a rapid light yield, with 80% of light yield within one crossing time (25 ns ...

3. Photon counting - Wikipedia

   en.wikipedia.org/wiki/Photon_counting

   The Hubble Space Telescope has a similar detector. Photon counting is a technique in which individual photons are counted using a single-photon detector (SPD). A single-photon detector emits a pulse of signal for each detected photon. The counting efficiency is determined by the quantum efficiency and the system's electronic losses.

4. Metal detector - Wikipedia

   en.wikipedia.org/wiki/Metal_detector

   U.S. Army soldiers use a military standard metal detector. A metal detector is an instrument that detects the nearby presence of metal. Metal detectors are useful for finding metal objects on the surface, underground, and under water. A metal detector consists of a control box, an adjustable shaft, and a variable-shaped pickup coil.

5. Transition-edge sensor - Wikipedia

   en.wikipedia.org/wiki/Transition-edge_sensor

   Optical image of four tungsten transition-edge sensors for near-infrared single-photon detection. Image credit: NIST. A transition-edge sensor (TES) is a type of cryogenic energy sensor or cryogenic particle detector that exploits the strongly temperature-dependent resistance of the superconducting phase transition.

6. Induction loop - Wikipedia

   en.wikipedia.org/wiki/Induction_loop

   An induction or inductive loop is an electromagnetic communication or detection system which uses a moving magnet or an alternating current to induce an electric current in a nearby wire. Induction loops are used for transmission and reception of communication signals, or for detection of metal objects in metal detectors or vehicle presence ...

7. Electrochemical fatigue crack sensor - Wikipedia

   en.wikipedia.org/wiki/Electrochemical_fatigue...

   An EFS sensor is first applied to the fatigue sensitive location on the bridge or metal structure, and then is injected with an electrolyte, at which point a small voltage is applied. The system subsequently monitors changes in the current response that results from the exposure of fresh steel during crack propagation.
