How to get a particle detector on a plane

You may have observed airplane passengers accompanied by pets or even musical instruments on flights. But have you ever been seated next to a particle detector?

Nanoantennas help detectors see more heat, less noise

Sandia National Laboratories researchers have developed tiny, gold antennas to help cameras and sensors that "see" heat deliver clearer pictures of thermal infrared radiation for everything from stars and galaxies to people, ...

Roman bronze cauldron unearthed in central Norway burial cairn

Sometime around 150-300 CE a person died at the place now called Gylland in the Gaula River valley, in southern Tr√łndelag county. After the body was cremated, the remains were laid in a bronze vessel. This was then covered ...

Lithium fluoride crystals 'see' heavy ions with high energies

Lithium fluoride crystals have recently been used to register the tracks of nuclear particles. Physicists from the Institute of Nuclear Physics of the Polish Academy of Sciences in Cracow have just demonstrated that these ...

Sensor

A sensor (also called detector) is a device that measures a physical quantity and converts it into a signal which can be read by an observer or by an instrument. For example, a mercury-in-glass thermometer converts the measured temperature into expansion and contraction of a liquid which can be read on a calibrated glass tube. A thermocouple converts temperature to an output voltage which can be read by a voltmeter. For accuracy, most sensors are calibrated against known standards.
