Magnet lensing
The magnetic lens allows pico-clusters to be contained in the void space between the anodes. The time in containment extends their life time which promotes energy gain through vacuum reactions. Once the clusters have ruptured, the negatively charged and now free electrons are subjected to Coulomb repulsion which results in deviations from the plotted vector potential because the vector potential lines are not parallel.
Electrons in the magnetic field are subjected to Lorentz force which gives them a spiral flight path. Furthermore, the Coulomb repulsion will be suppressed by the magnetic field, which results in few free electrons are left in the tube before the next burst of electrons from the cathode.
