I’m interested in the March 3, 2017 report. “In January, the LPPFusion research team completed the reassembly of FF-1, using a fresh 10-cm long tungsten anode and the existing 14-cm long cathode.” Does changing the relative length of the two electrodes change the location of the plasmoid? The newly improved ICCD camera should provide some answers. If the plasmoid can be formed above the anode instead of inside or very close to the anode then there should be less radiation damage to the anode. It doesn’t matter to a low repetition rate experimental machine but could make a difference in a commercial power unit.
Would changing the shape of the tip of the anode to a hollow cone or another geometry cause the plasmoid to form farther away from the anode?
