The Westinghouse Atom Smasher

Until 2015, there was a very important machine near the eastern edge of Forest Hills, close to Chalfant. It was called the Westinghouse Atom Smasher. This machine was a huge Van de Graaff generator and particle accelerator that could create five million volts of electricity!

The Atom Smasher was used from 1937 to 1958. Many important scientific discoveries were made using this device. Because of its historical importance, it was named an official historic landmark in 2010. However, the land where it stood was being prepared for new buildings, so the Atom Smasher was taken down in 2015. It was a big part of the Westinghouse Research Laboratories, which operated there from 1916 to 1956.
