Main Question or Discussion Point

Decades ago a massive neodymium bar was going to be used for measuring GW's.

I know noise was a problem. Anyone know what happened to this technology?

Sounded cool, a big bell at the resonance frequency of a GW.

The bar detectors were never sensitive enough by many orders of magnitude, so no gravitational waves were ever detected. That is why we switched to long Michelson Interferometer detectors.

cheers, thought it would be something on those lines.

still a bold idea, they must have learned a lot about noise reduction and signal extraction in the process I would imagine.
