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).
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.
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.
The largest air-insulated Van de Graaff generator in the world, built by Van de Graaff himself, is operational and is on display in the Boston Museum of Science. Demonstrations during daytimes are a popular attraction. More modern Van de Graaff generators are insulated by pressurized dielectric gas, usually freon or sulfur hexafluoride. During ...
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]
Van der Graaf Generator are an English progressive rock band, formed in 1967 in Manchester by singer-songwriters Peter Hammill and Chris Judge Smith and the first act signed by Charisma Records. They did not experience much commercial success in the UK, but became popular in Italy during the 1970s.
Other groups, such as Led Zeppelin and Van Der Graaf Generator used the bass pedals of the Hammond organ in place of a bass guitar for several of their recordings and for live performances. Other users included metal and hard rock bands such as Yngwie Malmsteen, Styx, and Francis Buchholz of the Scorpions, and Justin Harris of Menomena.
