Electron energy characteristics generated by the irradiation of ultra-intense laser pulses onto solid targets are controlled by using cone targets. Two important parameters characterizing the laser-cone interaction are introduced, which are cone angle and the ratio of the laser spot size to cone tip. By changing these parameters, the electron energy characteristics are controlled. They are optimized for fast ignition with the aid of 2D Particle-in-Cell (PIC) simulations.
