A load cell is a calibrated device for measuring force. In a tensile modulus experiment its output supplies the axial load used to calculate engineering stress.
An X-ray observatory used for high-resolution imaging and spectroscopy of astronomical sources. Its observations of the Perseus cluster reveal structure in the emitting intracluster gas around radio bubbles.[ref]
A space observatory that measured stellar light curves to discover exoplanets and constrain their exoplanet occurrence rate through exoplanet transit photometry.
A photogate detects interruption of a light beam. Timing that interruption and independently measuring the flag length gives its average speed during passage; the direction must be assigned separately.
A gas-filled particle detector using electron avalanche multiplication. Within its proportional operating range, the collected electric charge tracks the initial ionization, allowing more than a yes-or-no count.
A Potter-Elvehjem homogenizer mechanically disrupts biological tissue between a pestle and a surrounding tube.
