A rugged unit that will develop potentials up to 350, 000 volts on the polished, anodized dome. Provides the power to execute all the basic electrostatic demonstrations on an energetic and dramatic scale. When the pearshaped metal sphere is charged by touching it to the Van de Graaff, a larger charge can be removed from the narrow end than from the fat end. The amount of charge is tested by the deflection of an electroscope. What I particularly like about the Van de Graaff (or VDG) is that its a combination of a few discrete scientific principles and some mechanically produced current, making it an interesting study. The Van de Graaff generator is a classroom classic with a surprising heritage in cuttingedge particle physics. As well as making your hair stand on end, these machines were used to accelerate particles through millions of volts. Van de Graaff invented the generator to supply the high energy needed for early particle accelerators. These accelerators were known as atom smashers because they accelerated subatomic particles to very high speeds and then smashed them into the target atoms. A Van de Graaff generator is a device for making lots of static electricity. Static electricity is made from extra charges stored some place so that they cant move. Van De Graaff seeks to use simple, clear terms when explaining to his patients the care and treatment they are receiving, whether for acne, dermatitis. The Van de Graaff generator shown in Figure 13 is a mechanical device that produces an electromotive force. Invented by the American physicist Robert J. Van de Graaff in the 1930s, this type of particle accelerator has been widely used to study subatomic particles.
