What most people know about Van de Graaff generators
Static electricity
High Voltages, low currents
Learn about science, electricity
Fun!

Van de Graaff Generators What most do not know:
First electrostatic generator/accelerator to reach 1 MeV
First X-ray devices to treat cancer patients
Used in WWII in Manhattan Project to discover isotopes and by U.S. Navy to X-ray ordnance, welding, etc.
Still used today to sterilize food, implant ions in semiconductors, harden paint, and perform basic physics research and teaching

Van de Graaff Generators First cool hangout for media
and guests to see LOUD high voltage experiments since Tesla in Colorado and NYC.
While this was going on, MIT, Trump, Van de Graaff, Compton, and the government (at the TVA) were hashing out terms.

High Voltage Engineering Corp. Original Van de Graaffs are
still in use today at Brookhaven, Tennessee, Research Triangle, and more – especially the FN series.
Very durable.
Customizable.
Upgradable.

Where is it now? Original device from Round
Hill still working at the Museum of Science in Boston.
80+ years old.
Textolite is deteriorating.
