Scientists 'at the bleeding edge' with upgrade to CMS detector

The huge detectors providing a window to the world's tiniest particles are set for a $153 million upgrade, and a team of Purdue University scientists will play a key role—continuing the university's decades-long legacy ...

Radiation-detecting plastic gets ingredient to stay in the clear

Researchers at Sandia National Laboratories have identified a straightforward change to the formula for radiation-detecting plastic. The change prevents "fogging," which reduces the lifetime of the plastics used to detect ...

TAMA300 blazes trail for improved gravitational wave astronomy

Researchers at the National Astronomical Observatory of Japan (NAOJ) have used the infrastructure of the former TAMA300 gravitational wave detector in Mitaka, Tokyo, to demonstrate a new technique to reduce quantum noise ...

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.
