If memory serves, the van der graff generator at the Boston Museum of Science was literally used as a particle accelerator at MIT for decades (apparently built by the Van de Graaff). I think the generator itself was the accelerator and just needed to go through an evacuated tube to be used. > The largest air-insulated Van de Graaff generator in the world, built by Dr. Van de Graaff in the 1930s, is now displayed permanently at Boston's Museum of Science. With two conjoined 4.5 m (15 ft) aluminium spheres standing on columns 22 ft (6.7 m) tall, this generator can often obtain 2 MV (2 million volts). https://en.wikipedia.org/wiki/Van_de_Graaff_generator https://en.wikipedia.org/wiki/Van_de_Graaff_generator https://www.atlasobscura.com/places/worlds-largest-airinsulated-van-de-graaff-generator https://www.atlasobscura.com/places/worlds-largest-airinsula...
