bcrowell said:1H on 1H is not going to give you appreciable fusion -- the cross-section is super small. Getting a deuterium beam and/or a deuterium target does not sound easy to me as a DIY project.
[EDIT] Corrected an error above -- c.m. energy is 1/2, not 1/4.
Drakkith said:What are your goals for something like this jshine? I am currently attempting to build a Fusor at home. A fusor is similar to what you are thinking of, but it is not beam-target or beam-beam. I've got a 40kv power supply that should be fine for getting detectable fusion out of a Fusor. (Well, as long as it works...got it off ebay...)
Try www.fusor.net for more info on this or look it up on Wikipedia.

A Van de Graaff accelerator is a type of particle accelerator that uses static electricity to accelerate charged particles. It works by using a motor to continuously move a rubber belt, which builds up a high voltage charge on a metal sphere at the top of the accelerator. This high voltage is used to accelerate charged particles to high energies.
A Van de Graaff accelerator can accelerate a wide range of particles, including protons, electrons, and ions. It can also accelerate heavier particles such as alpha particles and nuclei of atoms.
Van de Graaff accelerators have a variety of applications in scientific research. They are commonly used in nuclear physics experiments to study the structure of atoms and nuclei. They are also used in medical applications, such as proton therapy for cancer treatment, and in industry to create high-energy beams for materials testing or sterilization.
One of the main advantages of a Van de Graaff accelerator is its ability to produce high-energy particles without the need for large and expensive magnets. This makes it a cost-effective option for many research facilities. Additionally, the particles produced by a Van de Graaff accelerator are very stable and can be precisely controlled, making it useful for a wide range of experiments.
One limitation of a Van de Graaff accelerator is that it can only accelerate charged particles, so it cannot be used for neutral particles such as neutrons. It also has a limited energy range compared to other types of particle accelerators. Additionally, the size and complexity of the accelerator can make it difficult to operate and maintain.
