>How would you go about magnetizing the grid? Tantalum and stainless steel are both non-magnetic, particularly if run hot. I suppose you could run a current through the grid using an isolated low voltage supply to create a magnetic field, but would this create the effect you are seeking?

I was conceiving of wrapping solenoids around the grid elements. If you use an isolated floating supply and standard magnet wire, you don't even need insulation. This would result in field lines perp to the grid elements, deflecting electrons away from them and increasing electron lifetime dramatically.
