A Weber bar is a device designed to detect gravitational waves, first devised and constructed by physicist Joseph Weber at the University of Maryland. The device consisted of aluminium cylinders, 2 meters in length and 1 meter in diameter , antennae for detecting gravitational waves .
Allegro was a ground-based, cryogenic resonant Weber bar, gravitational-wave detector [1] run by Warren Johnson, et al. at Louisiana State University in Baton Rouge, Louisiana. The detector was commissioned in the early 1990s, and was decommissioned in 2008.
The earliest type was the room-temperature bar-shaped antenna called a Weber bar; these were dominant in 1960s and 1970s and many were built around the world. It was claimed by Weber and some others in the late 1960s and early 1970s that these devices detected gravitational waves; however, other experimenters failed to detect gravitational ...
