Noun
Van de Graaff (plural Van de Graaffs)
(physics) Ellipsis of Van de Graaff generator.
For example, the Brookhaven National Laboratory Tandem Van de Graaff achieves about 30 million volts of potential difference. Source: Internet
The voltage produced by an open-air Van de Graaff machine is limited by arcing and corona discharge to about 5 megavolts. Source: Internet
A Van de Graaff generator terminal does not need to be sphere-shaped to work, and in fact, the optimum shape is a sphere with an inward curve around the hole where the belt enters. Source: Internet
In order to double the voltage, two generators are often used together, one generating positive and the other negative potential; this is called a tandem Van de Graaff accelerator. Source: Internet
In the Van de Graaff generator, the belt allows the transport of charge into the interior of a large hollow spherical electrode. Source: Internet
It consisted of a tandem Van de Graaff generator operating routinely at 20 MV, housed in a distinctive building 70 metres high. Source: Internet
