You’ll need an insulator for that, Brian. The x-ray collector works like a capacitor.
In what respect like a capacitor? The electrons knocked loose by X-rays are drained by grids between foil layers; I am suggesting use of the graphene for the grids. The last thing you want to do is insulate them.
The patent compares the converter assembly to a capacitor- the foils are your grids, collecting the electrons. Each of the foils is a different thickness to reduce the energy of x-rays with enough energy to penetrate them. Personally, this reminds me of control grids in a vacuum tube, all the way down to the biasing network.
Put another way, since the foils conduct very well, what is the gain of designing and producing another 1,000 or so conducting layers?
But no matter what the end design is, CVD is the only production process with even a chance of building these assemblies reliably. I suspect that this assembly is going to be the vast majority of the production cost.
