Parts of the chamber

In a chamber, there must be a few parts in order for the fusor to work:

1. High voltage feedthrough
2. Viewport
3. Grid

High voltage feedthrough

The hv feedthrough is what allows us to insert hv electricity into the chamber without disturbing the vacuum system. These parts can get very expensive, up to $1000 starting at about $100. Currently, I am using a automotive spark plug as my feedthrough because they are very cheap and require only a little bit of machining.

Viewport

 Viewports allow the spectator to view what is going on inside the fusor. In real fusors at higher voltages, these can be very dangerous because x-rays are released through them.

Grid

The grid is what is wired to the hv feedthrough attracts the air molecules it which are then ionized.
