A Van der Graaf generator is an electrostatic generator which uses a moving belt to accumulate very high amounts of electrical charge on a hollow metal globe to the top of the stand. It is also the name of a metal band.
The Van de Graff generator was named after Van de Graff, who invented it. A Van de Graff generator is a device used to store an enormous amount of electric charge (either positive or negative) on a metallic sphere so that a very strong electric field can be produced. This strong electric field can be used to accelerate charged particles like protons, alpha particles etc. In the Van de Graff generator, charges from an electric battery are separated and stored on a metallic sphere which is mounted on an insulating pillar.
A large rubber band spins, rubbing on a metallic dome. some electrons are transfered from the band to the dome, acting as static electricity. When, say Steve, touches the dome the charged particles will leap to him. Steve will experience a static shock.
he invented the first generator
Yes
Assuming you're meaning to check if the program works - run it with some test data that you know what the solution should be be if the program works correctly. If you get the expected result, the program is fine - if not - it needs de-bugging.

Bobbie van de Graaf was born in 1944.
Karel van de Graaf was born on December 4, 1950, in Rotterdam, Zuid-Holland, Netherlands.
Yes. Some of the larger units can create potential differences of several hundred thousand volts with ease, and the really big ones push several million volts. And they can do this with a good ability to deliver a big shot of current at that potential. A jolt from a Van de Graaf generator working in those ranges would be fatal.

You can build one for the cost of a motor, PVC pipe, rollers, belt, some wire and a couple stainless steel salad bowls...That could be around $30. See the link for one person's DIY Van de Graaf. You can buy one from Edmund Scientific for $500
Using a wooden sphere for the dome of a Van de Graaff generator is not advisable as wood is not a conductive material, which is necessary for the generator to function properly. A metal sphere or other conductive material would be more suitable for the dome of a Van de Graaff generator.
NO....a metallic dome must be used ,so that cahrges get accumulated on it...a wooden block(insulator) cannot do that..
Yes, negative ions can be accelerated using a Van de Graaff generator. The generator can produce a high voltage difference that accelerates the ions, regardless of their charge. The ions will be repelled or attracted according to their charge, gaining kinetic energy in the process.
The basic use of a Van de Graaf generator is to separate electric charges and build them up, frequently for demonstration purposes. A "big" version can be used to provide a burst of energy for generating X-rays, or for accelerating electrons or protons. The accelerated charges find some practical applications as well as some uses in scientific investigations. It's an electrostatic generator, and it will create a considerable difference of potential.
