Well here’s an amateur’s rough design. If its no good, you can tell me why and I can learn something!
Are we allowed to move the anode away from the cathode?
– The barriers have orifices to allow fluid circulation.
– The cathode edge ( and ideally its whole cylinder ) is positioned out of direct line from the fusion zone
– If need be, the anode can be simply shielded from direct line of the fusion zone too.
