Hollow Cones Fail to Guide Energetic Electrons to Fusion Fuel

Caption

These images from their simulations highlight the trajectories of randomly-selected electrons for a thin cone (left) and thick cone (right), each attached to a copper wire. Background colors show the strength of the electric fields pointing away from the cone and wire. For thin cones, the electric fields act to guide energetic electrons forward into the wire while for thick cones -- a more realistic case -- these fields are too distant to be effective. An animation of the simulation is available online at: http://www.physics.ohio-state.edu/~orban/cone_wire_final5mJ_4_5ps.avi.
