  A novel scheme for the creation of a convergent, or focussing, fast-electron
beam generated from ultra-high-intensity laser-solid interactions is described.
Self-consistent particle-in-cell simulations are used to demonstrate the
efficacy of this scheme in two dimensions. It is shown that a beam of
fast-electrons of energy 500 keV - 3 MeV propagates within a solid-density
plasma, focussing at depth. The depth of focus of the fast-electron beam is
controlled via the target dimensions and focussing optics.
