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 ).
The Van de Graaff generator is a simple mechanical device. Small Van de Graaff generators are built by hobbyists and scientific apparatus companies and are used to demonstrate the effects of high DC potentials. Even small hobby machines produce impressive sparks several centimeters long. The largest air-insulated Van de Graaff generator in the ...
The two most common types are the Van de Graaf generator invented by Robert Van de Graaff in 1929, and the Cockcroft-Walton accelerator invented by John Cockcroft and Ernest Walton in 1932. The maximum particle energy produced by electrostatic accelerators is limited by the maximum voltage which can be achieved the machine.
It was the first industrial Van de Graaff generator in the world, [9] and marked the beginning of nuclear research for civilian applications. [10] [11] Built in 1937, it was a 65-foot-tall (20 m) pear-shaped tower. [9] [12] It was essentially unused after World War II, and the main structure was laid on its side in 2015. [12]
A Van de Graaff generator, for classroom demonstrations 12" Quadruple Sector-less Wimshurst Machine (Bonetti Machine). An electrostatic generator, or electrostatic machine, is an electrical generator that produces static electricity, or electricity at high voltage and low continuous current.
In 1933, Round Hill was the site of Robert J. Van de Graaff's electrical experiments. Van de Graaff had been brought to MIT from Princeton in 1931 to develop a high voltage research facility. He built a 40-foot (12 m) tall Van de Graaff generator in an abandoned airship hangar on Round Hill. The purpose was to provide the energy to accelerate ...

Van de Graaff is a crater formation located on the far side of the Moon, on the northeast edge of Mare Ingenii. The crater is named for physicist Robert J. Van de Graaff, whose groundbreaking work includes the invention of the Van de Graaff generator. [1] Van de Graaff is one of the largest craters of Nectarian age. [2]
