I finished the plexiglass box for the HV power supply components. It is modeled after the original panel mounted Hummer V high voltage AC supply. A 1/2" thick plexiglass box 17" wide, 4.5" tall, 3.5" deep with a 1/4" thick plexiglass cover or flange that mounts in the original panel opening. The guages will be mounted an the cover. The two high voltage AC leads, chamber ground, and high voltage negative leads are surrounded by thick walled tygon liposuction vacuum tubing, (used) and pass through into the box with barbed hose connecters.
All the components fit in the box but they are a tad close (2" to 3"). I plan to seperate the some of the high potental difference contacts with 1/4' plexiglass "baffels" in the box.
Does anyone know the safe air gap for 10KV DC? Somehow I think quite long.
How much heat is generated by the high voltage components? What about cooling the box?
The base of the Hummer V has three 4" box fans in the back. The air cooled diffusion pump sits in the zephyr of one of the fans. I would be a relatively simple matter to rig a duct to cool the the box from one of the other two fans, but is it necessary?
