In summary, a Cockcroft-Walton Generator is a high-voltage DC generator that uses capacitors and diodes to multiply the input voltage. It works by using a voltage multiplier circuit and has applications in particle accelerators, X-ray machines, and nuclear physics experiments. Its advantages include simplicity, low cost, and high voltage conversion efficiency, but it has limitations in output current and voltage rating.

I found this generator online and I was wondering how this setup works.

http://en.wikipedia.org/wiki/Cockcroft–Walton_generator

How do the different stages up the voltage into dc? and just how do the capacitors and diodes actually work together to do this?

There's an explanation on http://www.blazelabs.com/e-exp15.asp.
 

What is a Cockcroft-Walton Generator?

A Cockcroft-Walton Generator is a high-voltage direct current (DC) generator that uses a series of capacitors and diodes to multiply the input voltage. It was invented by John Cockcroft and Ernest Walton in 1932.

How does a Cockcroft-Walton Generator work?

The Cockcroft-Walton Generator works by using a voltage multiplier circuit. The input voltage is first rectified by a diode, then stored in a capacitor. The capacitor is then discharged into the next stage through a diode, which increases the voltage. This process is repeated through multiple stages, resulting in a high output voltage.

What are the applications of a Cockcroft-Walton Generator?

Cockcroft-Walton Generators are commonly used in particle accelerators and X-ray machines. They are also used in high-voltage power supplies for cathode ray tubes and in nuclear physics experiments.

What are the advantages of using a Cockcroft-Walton Generator?

One of the main advantages of a Cockcroft-Walton Generator is its simplicity and low cost compared to other high-voltage generators. It also has a high voltage conversion efficiency and can produce a very high output voltage.

What are the limitations of a Cockcroft-Walton Generator?

Cockcroft-Walton Generators have a limited output current and are not suitable for high-power applications. They also have a voltage rating limitation due to the breakdown voltage of the capacitors and diodes used in the circuit.
