Unfortunate news out of Pittsburgh this week. The nearly 80-year-old, long defunct Westinghouse Atom Smasher has been toppled.

The five-story steel bulb was the first industrial particle accelerator ever built, and was the most powerful in the world when it was completed in 1937. Its unusual bulb shape is because it is an old Van de Graaff style electrostatic accelerator. The steel dome would build up a huge electrical charge, repelling positively charged ions down a beam tube onto an experiment or detector. It’s a design that today is mostly obsolete, but a few modern accelerators use a version of the technology.

The developer who owned the property, Gary Silversmith, had been trying to raise funds to turn the building into an education center. However with projected costs to refurbish its supporting brick structure nearing $2 million, repurposing the old facility was just not economically feasible.
“Right now the bulb is on the ground, but we are going to establish a
new concrete base for it, and keep it at the site, and have the bulb
repainted, including the ‘W’ for Westinghouse,” Silversmith said in an email.
He added that he is still working with the Westinghouse corporation and the Forest Hills school district to try and refurbish and repurpose the steel bulb in some capacity.
WTAE reported that the Westinghouse CEO Danny Roderick was disappointed at the destruction of the facility but is still hopeful that they can find a permanent home for the massive steel accelerator.
