Glenn’s 3-d rendition is great! The color is fine–that’s the color of the copper electrodes. We should use it in place of the diagram.

In terms of Rezwan’s question, yes, DPFs do differ from one another. First of all, most DPF’s have an outer electrode composed of several parrallel rods. But the DPF that the drawing was based on had a solid outer elctrode–a cylinder like the inner electrode. I have always used that because is makes a much clearer diagram in cross-section and I have never seen a good drawing for the multi-rod kind. Also, the Chile DPF tend to be very short. This depends on the duration of the pulse–shorter pulse, shorter electrode. We don’t yet know what the ideal pulse length is.

Also, the Chile shot is a bit small to see what is really going on. The electrodes are all in the center, very small and maybe not visible at this size photo. The big outer cylinders are ports inthe vacuum chamber. Maybe we chould crop it so the center area is bigger.

If Glenn could do a 3-d rendition with a circle of say eight rods, maybe we could compare them and see which looks better and clearer. But the one he already has is very good, I think.
