Step 4: Assemble The Deuterium System

Deuterium gas is used as the fuel for this fusion reactor. You will need to purchase a tank of this gas (unless you wish to do electrolysis on heavy water, this process will not be documented here but nothing more than a small Hoffman Apparatus is required - higher purity gas can be gotten from a compressed tank).

Attach a high pressure regulator directly to the tank, add an extremely fine-metering needle valve after this (or a laser drilled orifice in the range of 5 microns), then attach this to the chamber. A ball valve can also be installed between the regulator and the needle valve since needle valves are not shutoff valves.

See the attached diagram now updated with the deuterium handling system.

Where is deuterium bought?

I got mine from AirGas, there are several companies that can potentially provide it (if they are willing, often they are not)
i was looking at airgas and one of the required field was a company affiliation. i was wondering what i should put in.

It is hard to get deuterium. It takes some amount of luck unless you have a company to order through. It sounds like you got put on the "we don't want to sell to you because you're an individual" list. I'd suggest either going to a local AirGas specialty-gas location and try to order in person if you haven't already. Otherwise, try other companies.
