I thought I would post this picture of my best star mode. A diffusion pump is on the way which should get me into the sub-micron world of fusoring. When that happens, my current setup will be totally reconfigured.

Wow! What outer grid are you using? What is the seal between your bell jar and base plate?

Before I dismantle my fusor, I felt that it was important to take a quick photo of my star mode at best vacuum. My spherical outer grid suffered an assault by my son which it never recovered from. So I quickly put together a makeshift outer "ring" grid by bending and crimping some tig rod. It worked good enough for the photo. I still recommend a spherical outer grid for a demo fusor.

My baseplate is 5/8" thick alluminum plate from an alluminum supplier I found on E-Bay. It only cost me $15.00. I drilled and tapped the holes necessary for the hoses, TC gauge and HV feedthru. My sealant is only a small bead of Dow Corning Vacuum Grease.

I have archived this sucker. Beautiful! Deja Vu of fusor II, my old bell jar model. I can sympathize with the needed tear down. Sometimes a complete rework is in order to move to the next step or stage.
